RFR (JDK11/JAXP/java.xml) 8198548: Initialization race in com.sun.org.apache.xerces.internal.impl.xpath.regex.Token.getRange() on Token.categories

Wed, 16 May 2018 16:42:07 -0700 

Hi,
Please review a fix on synchronization. The real change is the double-checked locking, all others are s/Token.categories/tmpMap/g. 


All JAXP tests passed. Before the fix, the test attached to JBS failed 
only once for me after 10,000 runs and then a few 1000 runs (impossible 
to get one with only 20 runs as the comment mentioned).  The author of 
the original report put the actual pass rate at 99.994%. After the fix 
then, in theory it should be 100%, I've made a 100,000 run without 
seeing a failure.

Thanks,
