Hello
Today while trying to run acceptance tests on x86_64 I've found that
kernel tests fail from the first test in pure Jitrino.OPT (-Xem:opt)
mode. I've tried running simple hello world application, and it does not
work any more. The NPE happens in class loader code before the main class.
I know x86_64 is still not a very stable architecture, but this is
clearly a regression. I try to do all my commits checking on x86_64
Linux. Starting from today no program work at all. This is strange
considering that I didn't see any significant commits to Jitrino for the
last 2 days.
I've reproduced it on SuSE9 x86_64 and Gentoo x86_64. On SuSE10 x86_64
something even worse has happened, need to investigate if anything at
all works on it so far (I mean Harmony, the system itself is ok).
Here is the stack trace. If I understand it correctly, the code SIGSEGVs
in java.net.URLClassLoader.getPermissions and the signal is treated as
hardware NPE.
