IBM's developerWorks has released the Pattern Modeling and Analysis Tool for Java Garbage Collector (PMAT) 1.2. "PMAT analyzes IBM verbose GC traces by parsing the traces and building pattern models. PMAT recommends key configurations by executing a diagnosis engine and pattern modeling algorithm. If there are any errors related with Java heap exhaustion or fragmentation in the verbose GC trace, PMAT can diagnose the root cause of failures. PMAT provides rich chart features that graphically display Java heap usage."
