Abstract
Methods and apparatuses for deferring, or delaying, the throwing of exceptions are disclosed. In one aspect of the present invention, an exception is raised during an invocation of a first object within an object-based system. The exception may be processed by catching the exception and making a first copy of the exception. Making the first copy of the exception includes storing the first copy of the exception in a dynamic memory. The first copy of the exception may then be processed by creating a runtime copy of the exception that is stored on an execution heap. The runtime copy of the exception may is then caught. The first copy of the exception is deleted from the dynamic memory, and the caught runtime copy of the exception is reprocessed. In one embodiment, processing the first copy of the exception includes throwing the first copy of the exception as a system exception. In such an embodiment, throwing the first copy of the exception as a system exception causes the runtime copy of the exception to be created.
