Assignee: Dag H. Wanvik  (was: Kathey Marsden)
  Labels: derby_backport_reject_10_8  (was: )

Assigning back to Dag and marking backport reject. Merge is not automatic 
because of other DirFile4 changes so did not make an effort to merge manually.  
If really needed I think it could be merged manually, but won't do that now.

Attachment: d5498a-debug.stat
d5498a-debug.diff
d5498a.diff
d5498a.diff

Not sure where the interrupt comes from here. In any case, there is a small 
time-window inside DirFile4#getExclusiveFileLock where we use a NIO file 
channel and the code is not ready to handle interrupts. 

Enclosing a patch, d5498a, which plugs this hole by our usual approach when 
seeing interrupts: make a note, clear the thread's interrupt flag, and then 
retry the operation.

The companion patch which I also upload contains additional instrumentation 
code to provoke an interrupt of the thread just before we attempt to get the 
exclusive lock as a test of the new logic. See code bewteen "test code being" 
and "test code end". 

Running regressions.
