IndexWriter does not do the right thing when a Thread is interrupt()'d
----------------------------------------------------------------------
Key: LUCENE-1573
URL: https://issues.apache.org/jira/browse/LUCENE-1573
Project: Lucene - Java
Issue Type: Bug
Components: Index
Affects Versions: 2.4.1, 2.4, 2.3.2, 2.3.1, 2.3, 2.2, 2.1, 2.0.0, 1.9
Reporter: Michael McCandless
Assignee: Michael McCandless
Priority: Minor
Fix For: 2.9
Spinoff from here:
http://www.nabble.com/Deadlock-with-concurrent-merges-and-IndexWriter--Lucene-2.4--to22714290.html
When a Thread is interrupt()'d while inside Lucene, there is a risk currently
that it will cause a spinloop and starve BG merges from completing.
Instead, when possible, we should allow interruption. But unfortunately for
back-compat, we will need to wrap the exception in an unchecked version. In
3.0 we can change that to simply throw InterruptedException.
