JCS 2.0 beta 1 throws InstanceAlreadyExistsException while redeploying

Redeploying an ear file on Geronimo 2.2.1 results in a InstanceAlreadyExistsException, refering to already existing JCSAdminBean.
Deploying on a restarted app server works fine though. Removing the ear and deploy it again does also throw the exception.
Seems like the bean is not being removed when the app gets undeployed.

The affected version is beta1, but this can not be selected in the drop-down.
