14. java.lang.OutOfMemoryError: PermGen space    forum.hibernate.org

Just a thought, maybe you wanna up your available perm space? -XX:MaxPermSize=128m or larger. Also on a 32-bit VM you won't be able to use anything more than about 1500m or so... Use 1.6 if you can and start with the min/max/maxpermsize as your only tuning options and go from there. Just my 2 cents.
