JDK-7121110 - JAXP 1.4.6 for 7u4
Description
javax.xml.parsers.FactoryFinder.find(String, String), revision 3037 contains a double checked locking bug.

The simple solution is to make static boolean field "firstTime" volatile and move the assignment "firstTime = false;" after the call to "cacheProps.load(ss.getFileInputStream(f));"

I did search for this bug, but can never seem to get good information out of JIRA's search feature.  Please excuse me if I have submitted a duplicate.

EVALUATION Fixed in jaxp 1.4.5. Will integrate into 7u2.

EVALUATION This bug was filed under 6, targeted for JAXP 1.4, but for some reason showing up in OKO query for bad deferrals, hence assigning RC7-defer-request. If this is a bug in OKO please let us know, then we could file a bug against the tool accordingly. Also it would be good to share the "query criteria" for bad deferrals.
