Write heap dump on OutOfMemoryError in Eclipse

Add below parameter to vm arguments of JVM.

This writes heap dump on OutOfMemoryError to your eclipse directory.
Say for example, if your working eclipse directly is "D:\Work\eclipse", there can find hprof extension file. It looks like below.
ex: java_pid1864.hprof
1864 represents running javaw process id.

It would be useful to analyze the cause using using memory profiler tools ex: Eclipse MAT, JProfiler and YourKit
