Subject Re: [JENKINS] Lucene-Solr-trunk-Windows (64bit/jdk1.8.0-ea-b98) - Build # 3067 - Still Failing!
Date Tue, 23 Jul 2013 17:37:00 GMT
I think this must be a JVM bug?

The child thread only exits its loop once finish is set to true.

But the parent thread only sets finish to true once it's done interrupting.

And the child thread clears the interrupt and then calls CheckIndex.

So it's impossible for CheckIndex to receive an interrupt from the
parent thread.

I think?
