Marcel Reutegger updated JCR-1272:
----------------------------------

    Attachment: JCR-1272.patch

Moved getItemState() to the top of the method. This ensures that the state reference is still valid even if the property is discarded after the sanityCheck().

> Running ConcurrentReadWriteTest (NUM_NODES=5, NUM_THREADS=3, RUN_NUM_SECONDS=120) resulted in a RepositoryException calling Property.getValue():
> javax.jcr.RepositoryException: Internal error while retrieving value of b3fc1ea8-3364-4236-bcc7-dea0baf90640/{}test: null: null
> Debugging shows that it is a NullPointerException:
> java.lang.NullPointerException
> 	at org.apache.jackrabbit.core.PropertyImpl.getValue(PropertyImpl.java:481)
> 	at org.apache.jackrabbit.core.ConcurrentReadWriteTest$1$1.execute(ConcurrentReadWriteTest.java:68)
> 	at org.apache.jackrabbit.core.AbstractConcurrencyTest$Executor.run(AbstractConcurrencyTest.java:110)
> 	at java.lang.Thread.run(Thread.java:619)
> It's probably the state which has been discarded after the sanityCheck().
