Hi Andre,
I am not kidding.
My application has only 8 to 10 classes. I checked the heap using IBM
heap analyser and my objects are not leaking memory.
I am guessing that this is a bug in tomcat 7. Let me know in case you
can make any sense out of the trace.

You are kidding us, right ?
But just in case you are not, what is the part which you do not
understand in
"java.lang.OutOfMemoryError: Java heap space".
