Disclosed are apparatus and methods for managing image storage. An image source of a computing device can include one or more functions and a reference to image views for an image object, such as a bitmap object. The image object can include a reference to first storage that stores an image. The image source, the reference to the image views, and the image object are stored in a managed portion of memory. The first storage is stored in an unmanaged portion of memory differing from the managed portion. The computing device displays the image. Upon determining to discontinue displaying the image, an unbind function of the image source is called. The image source responsively discontinues display of the image. The image source receives an indication that the image views are solely weakly referenced. In response to the indication, the image source deallocates the first storage.

In general, techniques and systems for transmitting media objects to a media sharing service are described. In one example, a method includes generating, by a computing device, a unique identifier that identifies a media object and is associated with a placeholder object, wherein the media object is of a higher fidelity than the placeholder object, and generating, by the computing device, a media share request that commands a media sharing service to create a network-accessible post, wherein the media share request comprises the unique identifier and the placeholder object. The method also includes transmitting the media share request to the media sharing service and subsequently transmitting the media object and the unique identifier to the media sharing service, wherein the unique identifier enables the media sharing service to replace the placeholder object in the network accessible post with the media object once the media object has been received.

Disclosed are apparatus and methods for loading images. A request can be received at a computing device to display a plurality of images on the computing device. In response to the request, the computing device can load, in parallel, the plurality of images into storage of the computing device. The computing device can determine whether an image of the plurality of images is to be used. In response to determining that the image is to be used, the computing device can mark the image as loaded. In response to determining that the image is to not be used, the computing device can mark the image as no-image. Only images marked as loaded can be provided for display.

A method for providing a service on a device. The method includes instantiating a service provider that provides the service, where the service provider implements a service provider interface (SPI) corresponding to the service and where the SPI is defined by a service provision framework for providing services to Xlets. The method further includes using the service by a first Xlet, where the first Xlet uses the service provider interface (SPI).

Method and system for providing services

A computer-implemented method and computer-readable medium for providing object-oriented communication between isolates is described. A request is received from a requesting Xlet for a remote reference to an exported object in a first isolate, the exported object having been exported by an exporting Xlet. A plurality of object registries are searched for the remote reference, each of the object registries being in a respective isolate. The remote reference is retrieved from one of the object registries and the remote reference is forwarded to the requesting Xlet.

Techniques for interpretation of DVD assembly language programs for television (TV) receivers operating in Java TV environments are provided. The techniques can be used to implement a Java-based command/control enabling system. The Java-based command/control enabling system can be implemented as a Java-based DVD assembly language interpreter which interacts with various modules including video, audio, graphics overlay, and remote control modules. As such, the Java-based command/control enabling systems can provide similar command/control functions as those provided by DVD systems.

Disclosed are methods and apparatus for managing resources. In general terms, a resource manager manages resource consumption of several resource entities which are each capable of consuming resources. The resource manager tracks the availability of such resources and determines whether a resource is critically short or reaches a particular usage level. When a resource becomes critically short or reaches a particular usage level, the resource manager selects one or more resource entities based on one or more criteria. For example, a resource entity which has the least restrictive resource usage policy or state is selected. The resource manager then requests that the selected resource entity changes its resource usage state to a more restrictive state. Of course, when resource usage reaches an acceptable level, the resource manager may also inform each resource entity (or previously selected resource entities) that they may set their resource consumption state to a less restrictive state.

Disclosed is a method for managing resource usage of a particular resource by a set of related code, such as code executed on behalf of a downloaded applet. A resource indicator is associated with the related code, and the resource indicator indicates an amount of resource usage of the particular resource by the related code. The resource indicator is updated when the related code increases or decreases its collective resource usage of the particular resource.

Apparatus, methods, and computer program products are disclosed for a process of terminating a thread in a clean, certain, and forcible manner. A thread is forcibly terminated in such a manner that data structures in the system are not left in an inconsistent state and the overall system status is not damaged. The methods and systems described are for terminating a thread in a computer language execution environment. Methods are implemented in an interpretive loop executing in a language that is interpreted and in runtime support libraries in a language that are not interpreted. A method of forcibly terminating a thread in a computer language execution environment is described. A thread receives a terminate thread command. The thread has associated with it a termination flag, a value of the termination flag being immutable once set, and one or more monitors. The termination flag is then set for the thread. An exception is then propagated in the execution environment thereby indicating termination of the thread. The exception handler and the finally clause of the thread is ignored during thread termination. The monitors associated with the thread are then exited.

Clean thread termination

Disclosed is a method for executing a remote method. Each argument of the remote method is wrapped when the argument is a remote object (e.g. the argument's declared class implements a remote marker interface). However, each argument of the remote method is copied when an argument is not a remote object. The remote method is invoked using the wrapped or copied argument(s) (e.g. the wrapped or copied arguments are passed to the invoked method). A result of the invoked remote method is then wrapped (e.g., prior to being passed to the process that is receiving the result) when the result is a remote object (e.g., the result's declared class does not implement the remote marker interface). In contrast, the result of the remote method is copied (e.g., the copy is then passed to the process that is receiving the result) when the result is are remote object.

Apparatus and methods for communicating between resource domains

In one aspect of the invention, the frames of a thread stack that associated with the misbehaving code are popped from the thread stack. Exception handling code is allowed to execute for trusted code by popping the trusted code frame via processing an exception, but exception handling is not allowed to execute for untrusted code. In a second aspect, frames are popped on all thread stacks of all threads that are associated with the misbehaving code. Threads are generally deemed to be associated with the misbehaving code when the threads share a same object or the same resources as the thread that is associated with the misbehaving code.

Apparatus and methods for preventing denial of service attacks

Methods and apparatus for implementing priority inversion avoidance protocols and deterministic locking where an API is used to select objects in a multi-threaded computer system are disclosed. In one aspect of the invention, an enhanced monitor is associated with one or more selected objects by way of an associated API. The enhanced monitor is arranged to set behavior for a lock associated with the selected objects as determined by a user defined behavior object included within the enhanced monitor. In this arrangement, only the selected one or more objects are associated with the enhanced monitor.

Real time synchronization in multi-threaded computer systems

Techniques for analyzing object-oriented computer programs are provided. A snapshot of the objects that are active at a specific point in time during execution may be stored. An analysis tool may be utilized to generate hypertext documents that allow a user to analyze the active objects. Additionally, a user may compare two different snapshots of active objects at two different run-times so that, for example, new instances of a class may be easily identified.
