(Possibly) Caching(???) issues with TestFiltering and RequiredFieldsTest (and
few more)
----------------------------------------------------------------------------------------
Key: SOLR-2673
URL: https://issues.apache.org/jira/browse/SOLR-2673
Project: Solr
Issue Type: Bug
Reporter: Uwe Schindler
With Java7 (b147) Solr tests fail, seems to be because of caching (maybe
ConcurrentLRUCache violates Java Memory Model, which can be seen in Java 7
only):
Example TestFiltering (passes sometimes):
{noformat}

It is definitely not a Hotspot issue, as it also happens with -Xint and -Xbatch.
