Description Guido Jäkel 2010-09-15 15:46:27 UTC

I would like to suggest to mask out Java 1.6.0.20 from portage (and to stabilize .21 or re-offer .17) and/or send out a Gentoo news announcement or any other adequate steps because of IMHO *very* serious low level problems rised by some failed improvements to use processor features like SSE -- please compare to http://www.oracle.com/technetwork/java/javase/bugfixes6u21-156339.html. 

Of course, maybe others should confirm such problems.

In my case, after an update from 1.6.0.17, the JVM of a otherwise completely unchanged tomcat production environment crashes after just a couple of hours with a JVM Fatal Error inside libjvm.so. This never happens for years before.

Oops, looks like stabilization bug was filled without arch teams in CC. So we will stabilize .21. Sorry for the trouble, please unmask .21 locally till it's done.
