Wherever we catch & suppress Throwable we should not suppress
ThreadInterruptedException
----------------------------------------------------------------------------------------
Key: LUCENE-3150
URL: https://issues.apache.org/jira/browse/LUCENE-3150
Project: Lucene - Java
Issue Type: Bug
Reporter: Michael McCandless
Priority: Minor
Fix For: 3.3, 4.0
In various places we catch Throwable and suppress it, usually in exception
handlers where we want to just throw the first exc we had hit.
But this is dangerous for a thread interrupt since it means we can swallow &
ignore the interrupt.
We should at least catch the interrupt & restore the interrupt bit, if we can't
rethrow it.
One example is in SegmentInfos where we write the segments.gen file... there
are many other examples in SegmentInfos too.
