To André; it's rather seldom where an extra GC would help in a situation
like this: GC will anyway have run (possibly several times) before the
OutOfMemoryError is thrown. The issue is that some class is packratting
recerences to objects no longer needed - and as there's someone still
referencing these objects, they cannot be freed by GC.
I understand. But that jmxsh can do more than just trigger GCs.
I'm not a Java programmer really, but this looked to me like an easy
external tool, maybe able to do from the outside what you propose to do
from the inside. It may be that none of that is useful, but it may be
worth having a look.
One limitation is since it uses the JMX interface of the JVM, I think
you need at least a JVM 1.5.
