JCR2SPI testNodeIdentity calls Node.isLocked()

[David Rauschenbach]

I implemented an SPI that does not support locking. However, the TCK
api,NodeTest testNodeIdentity() method calls isLocked(), which invokes
getLockInfo on my SPI, from which I throw
UnsupportedOperationException(), because I make no attempt to support
locking.
 
Am I misunderstanding anything? Or should the unit test tolerate an
UnsupportedOperationException before comparing isLocked() ?
