> The Websale example wrapped in a simple for-loop in standalone app. reveals what resembles a memory leak. Performance degrades severely as the JVM starts to do some expensive gc after 4000 iterations. At that time the JVM consume more than 274Mb of ram (JVM not started with special -X options!)
> Problem occurs with HSQLDB as well as Sybase db.
> The code to reproduce this problem has been posted here http://www.jboss.com/index.html?module=bb&op=viewtopic&t=99440
> Iter.    ms (per iter.)
