A synchronized JAVA debugger maintains synchronization between a JAVA source file in the debugger current working directory and a corresponding JAVA stored procedure in a database to be debugged. The debugger includes fetching module, storage module, display module, and execution module. The fetching module fetches a corresponding JAVA source file for a JAVA stored procedure from a database. The display module displays a recompile option, as a button, menu, or command line interface. In response to selection of the recompile option in the user interface, the execution module terminates the debugging session, sends a modified JAVA source file to the remote target JAVA Virtual Machine (JVM) and instructs the remote JVM to recompile the JAVA stored procedure using the modified JAVA source file before a new debugging session is started. Communication between the debugger and the remote database is by sending and receiving JAVA Debug Wire Protocol (JDWP) command packets.

Synchronized java debugger

A client debugger application or a virtual machine includes a receiving module configured to receive a command packet of a debugging protocol from a computer. The command packet includes an identifier (ID) field. The client debugger application or the virtual machine also includes a parsing module configured to parse an ID from the ID field. One byte of the ID field doubles as a command set value and another byte of the ID field doubles as a command value. The client debugger application or the virtual machine further includes a debugging module configured to use the parsed ID, command set value and command value to perform at least one debugging operation.

Modified implementation of a debugger wire protocol and command packet

Embodiments of the invention provide systems and methods for optimizing handling of breakpoints in a debugger agent. Embodiments generate an additional modified bytecode copy that includes location indexes associated with breakpoint requests at the breakpoint locations. The location indexes may correspond to a location in a data structure in which the breakpoint information (e.g., request identifier and associated location information) is stored. The location index identified by the additional bytecode copy for a breakpoint may then be used to directly access the appropriate location in the data structure for generating a desired reply packet. Thus, the location index may effectively allow the debugger agent to generate the reply packet without searching through a complex data structure for the relevant request information.
