I've got a test install of Vibe, and when I try to do an LDAP sync, with the option to automatically create group profiles, I get an error in catalina.out:

2014-01-21 21:07:27,272 WARN [http-8080-1] [org.kablink.teaming.spring.web.portlet.DispatcherP ortlet] - Handler execution resulted in exception - forwarding to resolved error view
java.lang.ArrayStoreException

And only 10 groups are created.

After some prodding from other forum posts, I checked the Java heap settings, and the Xmx setting is 5GB; There are 8 GB assigned to the VM. I have about 3500 user accounts (they seem to be importing fine) and about 100 groups. The DB is MS SQL 2008 R2.

The whole error is:
