Hello,
I had some problem with this issue:
https://issues.apache.org/jira/browse/LUCENE-2239
I was getting ClosedByInterruptException even though my application was
not calling Thread.interrupt() anywhere.
There were 2 scenarios of getting this exception:
class MyThread extends Thread {
public void run() {
// ...
update();
}
private void update() {
// some loop
otherclass.getIndexWriter().addDocument(doc);
otherclass.getIndexWriter().commit(); // <-
ClosedByInterruptException here
}
}

First try to find some workarund was by moving IndexWriter.commit call
somewhere before last line and it worked, ClosedByInterruptException was
not thrown anymore, however ClosedChannelException was thrown in other
thread when using IndexSearcher(NRT) after mythread ended
normally(without interrupt). I also tried to put some Thread.sleep() on
end of run(), but still it didn't help.
Finally i solved the problem by making mythread reusable. This is not
perfect solution for me, but for now it's working.
On note which may be important: MyThread is loaded using URLClassLoader
Conclusion is that you can't access NIOFSDirectory in thread which will
end normally or by interrupt. It happened in 3.3.0.
Thanks
