Embodiments of the invention provide systems and methods for optimizing handling of breakpoints in a Java debugger agent. Embodiments provide a novel command that allows execution of the application in the debugger to stop or break at the beginning of a next called function or method (e.g., a 'break on next called function' or 'BNCF' command). When the BNCF command is given to the debugger, a flag may be set in the interpreter of the virtual machine to which the debugger is attached. On encountering a new method or function call, the flag is examined by the interpreter to determine whether it should stop or break in that call. If the flag is set, the interpreter will stop; otherwise the interpreter proceeds.

Break on next called function or method in java debugger agent

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.
