Nick Tuckett commented on JCR-3438:
-----------------------------------

By UserTransaction I mean an equivalent of UserTransactionImpl.

And as for "real world", this is very definitely a real world application! It 
may be that we're abusing Jackrabbit/JCR support for XA, however...

> When outside a transaction, LockManager.addLockToken() calls 
> org.apache.jackrabbit.core.lock.LockManagerImpl.addLockToken(). This sets the 
> lock holder, and if the LockInfo object is actually an InternalLockInfo 
> object, it adds that object as a session listener. This means that the 
> LockInfo object is notified when the session is logging out, whereupon it 
> causes the session to release the lock token.
> When adding a lock token inside a transaction, the underlying implementation 
> calls org.apache.jackrabbit.core.lock.XAEnvironment.addLockToken(). This sets 
> the lock holder on the LockInfo object but does not add it as a session 
> listener. Consequently the lock token remains owned by the session, even when 
> the session finishes logging out.
> Subsequent attempts to get the lock token in other sessions using the same 
> credentials then fail.
