New Revision: 937309
URL: http://svn.apache.org/viewvc?rev=937309&view=rev
Log:
Fix https://issues.apache.org/bugzilla/show_bug.cgi?id=49143
Threading / initialisation issues. Not all were valid. Make them volatile
anyway so FindBugs doesn't complain.
Fix some additional issues - use of valueOf() - found along the way
