Method and system for analyzing memory leaks occurring in java virtual machine data storage heaps

摘要

An invention is disclosed for analyzing memory leaks occurring in Java Virtual Machine (JVM) data storage, consisting of a dynamically modifiable JVM “profiler” and an “object tracker” tool for analyzing the output from the profiler. Specifically, a method and system is disclosed for programming a JVM profiler used to analyze and correct memory leaks in stored data heaps, consisting of a program segment (or “stub”) initialized by the JVM application program interface to determine the parameters to be passed to the main profiler memory leak analysis program logic, which is then initialized by the stub to examine a minimal number of “heap dumps” in order to identify data elements or objects for the existence and/or correction of memory leaks. Updated information on data elements or objects can be requested from the profiler as needed by use of the object movement tracking option to record the details of subsequent changes in data memory storage status once a heap dump has been obtained.
