Jukka Zitting resolved JCR-3063.
--------------------------------
Resolution: Fixed
I restored the JCR-2171 fix in revision 1176465 to prevent the deadlock. In the
same revision I added explicit checks against the NPEs and CMEs thrown by the
test case. The CMEs are avoided by explicit synchronization and NPEs cause
InvalidItemStateExceptions instead.
A more thorough solution would probably be preferable, but at least the current
solution avoids the RuntimeExceptions, so I'm re-resolving this as fixed for
now.
I also merged the change to the 2.2 branch in revision 1176482 so we can still
ship this in 2.2.9.
