JSR170 says:
Lock.getLockToken():
"May return the lock token for this lock. If this Session holds the lock token for this lock, then this method will return that lock token. If this Session does not hold the applicable lock token then this method will return null."
Session.addLockToken(String lt):
"Adds the specified lock token to this session. Holding a lock token allows the Session object of the lock owner to alter nodes that are locked by the lock specified by that particular lock token."
and:
"Note that, as mentioned above, any user with the correct lock token assumes the power to remove a lock and alter nodes under that lock. It does not have to be the lock owner."
If i remember the discussion regarding the locking correctly, it was decided, that the locktoken is turned to any session, that contains the proper token. And: the Lock.getLockToken() is the only way to find out, whether a given session is allowed to modify a locked node (in contrast to the isLocked() method).
I have the impression, that the current implementation does not respect this:
Lock.getLockToken() passes the call to the LockInfo object. The latter performs the following check:
public String getLockToken(Session session) {
if (session.equals(lockHolder))
return null;
}
where the lockHolder is set to a particular session in consequence to Session.addLockToken but only if the lockHolder is null... otherwise the call it is ignored (LockManagerImpl line 468).
however, from the above quotes, i would rather expect, that the method should check, if the given Session holds the lockToken associated with this lock.
