Is there any parameter that says to JVM to make a heap dump (objects)
on OutOfMemoryError? I've tried to use -Xrunhprof with :net= option,
but application becomes unacceptable slow. I need something that works
without invocation of JVMPI and makes dump only when exception occurs.

I want to make a method that has to be executed when the user presses on the
enter key when the focus is on a JList. Because the list hasn't got an
actionlistener i don't know how to do it. I also want to make a method when
the user presses the delete key. can anybody help me with ...
