Yonik Seeley commented on SOLR-2673:
------------------------------------
Hmmm... notice the "numFound":5
There are only 4 documents added in this test.
If I add a clearIndex() at the top of the test method, everything is fine.
But why would that be necessary?
It looks like with Java7, that the test methods are not being run in the order
they are declared in the file.
That's probably the root cause of the other Solr test failures with Java7 too.
