Without more information, it's impossible to tell whether you have a memory leak, or whether you simply have too small a value for "maxmem" in the JVM. When the heap is too small or the current size might not be suitable for your application. Sometimes the JVMs code optimization causes Native OutOfMemory or the Crash…So in this case we can disable the Code Optimization feature of JVM. (Note: disabling the Code Optimization of JVM will NetBeans also has a nice plug-in (http://netbeans.org/kb/articles/nb-profiler-uncoveringleaks_pt1.html).
