[jboss-user] [JBoss Cache: Core Edition] - NullPointerException with mvcc

[stef_user]

I'm getting NullPointerException when i'm trying to remove a parent and a child node in the same transaction. The parent is in the cache but the child isn't. It seems like when the parent is removed it tries to remove the child too but the node doesn't exists.

Here is the stack trace:
