Hello, I am using Wicket 7 + Spring 4.x + Hibernate 4.x (recently migrated from Wicket 1.4).
Since deployment of the app on JBOSS, the application is crashing with OutOfMemory error for PermGen. We are at the point of rolling back to 1.4 as application was working fine without such issue; doesn't necessarily mean Wicket 7 is an issue. There is OutOfMemory error reported with Wicket+Spring for Wicket 6.20, but the issue status shows fixed. JBOSS application server PermGen is 512MB, so doesn't seem that be an issue. Here is the stacktrace (First and Second). Second seems to be the result of First one. Could anybody shade some light? I ran with some load on my local (tomcat as well as on JBOSS) and monitored using VisualVM. PermGen is remaining between 20 and 100 MB.
