I would suggest that committers using a Sun VM run with the default
heap settings and add the command line argument
-XX:+HeapDumpOnOutOfMemoryError to their eclipse.ini (after -vmargs).
This will cause a heap dump to be written to disk when an
OutOfMemoryError happens (and causes no overhead until then). Should
you end up with a heap dump, it can then be analyzed using
http://wiki.eclipse.org/index.php/MemoryAnalyzer .
