Java: finding what uses all memory

Question

I have a Java application that runs out of memory, but I have no idea what code allocates memory. Is there an application with which I can test this? I am using Eclipse.

Answer 1

Since you are using eclipse, I would recommend the Eclipse Memory Analyzer plugin . This tool works great and will even provide a report with likely suspected leaks. I looked at heaps of 1G soil without any problems. I just use jconsole included in the JDK to get a dump.

Also here is a great blog about using the tool by one of the authors of this tool.

It is also free.
