I have this exception when JBC is trying to fetch objects from database that are larger than 4kB.
I have read the following:
http://jira.jboss.com/jira/browse/JBCACHE-320
Hany Mesha writes that it is working for him for objects with large sizes with minor tweaking. I wonder what he mean by that :)
Any sugestions are welcome.
