Uwe Schindler updated LUCENE-4245:
----------------------------------
Attachment: LUCENE-4245.patch
Improved patch, much simplier. close() is no longer interruptible (throws no
exception ThreadInterruptedException), if interrupted it just cancels
unfinished merges and finishes earlier.
I applied this patch and now on my slow-IO windows system no Solr tests are
failing anymore, except ZK ones, which happens seldem here. With unpatched
trunk, I get no passing test run at all. It seems that on slow IO systems,
Jetty more often interrupts IndexWriter while closing.
I will commit this if nobody objects tomorrow morning.
> IndexWriter#close(true) should either not be interruptible or should abort
> background merge threads before returning
