Jinwoo Hwang, an IBM software engineer who is a member of WebSphere Application Server Technical Support Team, based in Research Triangle Park, has released HeapAnalyzer 1.3.5 – allowing the finding of a possible Java heap leak area through its heuristic search engine and analysis of the Java heap dump in Java applications.
HeapAnalyzer analyzes Java heap dumps by parsing the Java heap dump, creating directional graphs, transforming them into directional trees, and executing the heuristic search engine.
Java heap areas define objects, arrays, and classes. When the Garbage Collector allocates areas of storage in the heap, an object continues to be live while a reference to it exists somewhere in the active state of the JVM; therefore the object is reachable. When an object ceases to be referenced from the active state, it becomes garbage and can be reclaimed for reuse. When this reclamation occurs, the Garbage Collector must process a possible finalizer and also ensure that any internal JVM resources that are associated with the object are returned to the pool of such resources. Java heap dumps are snap shots of Java heaps at specific times.
The HeapAnalyzer tool can be donloaded here.
