Indeed reverting it has us back to the nominal status (a couple of failures).
Tom, I presume there was a very good reason for installing such a potentially
destabilizing patch a few days before the prerelease? What amount of testing
did it undergo before being backported?
Still, we are a bit stuck on SPARC/Solaris because there is not much interest
for that platform among the Java hackers (for SPARC/Linux either, I think).
AFAIK the only Java patches aimed at fixing problems there have been posted or
initiated by me. So I suspect nobody will step up to investigate what broke.
I understand that Java on SPARC is not a priority, but I think in such extreme
cases Java hackers should coordinate with the platform maintainers that try
to keep the Java compiler healthy on their architecture, despite the huge tax
of CPU cycles this entails. These CPU cycles should not be simply wasted.
