Tool for debugging hangs in java application

Question

I\'ve got a java application that half the time just hangs, and the other half the JVM crashes. Is there a tool I can use to see what\'s going on that makes it hang and/or c

Answer 1

In these cases(hang, freeze, ...) you have to analyze an heap dump to try to figure out what's happening in your application , you can use JVisualVM to take the dump, or you can add the appropriate JVM parameter to dump the content of the heap in the case of a crash.
