retargeted bug to java.util:i18n, the right mailing list seems to be i18n-dev.

Hi All,
This bug could be fixed by comparing the Class Loader with a blank static volatile Object (defined outside the method scope) at the end of the getBundleImpl class. E.g. ----------------------------------------- +1322 /** * volatile reference object to guard the ClassLoader object * being garbage collected before getBundleImpl() method completes * the caching and retrieving of requested Resourcebundle object */ private static volatile Object vo = new Object();
+1400 //Should never be true. Using the loader here prevents it being GC'd. if (loader == vo) throw new Error("Unexpected error."); ----------------------------------------- Will upload a webrev after debate. - Adam Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
