java hangs then crash in libc6/kernel

[Dmitriy Geels]

Binary package hint: linux-source-2.6.22

this is not actually kernel crash -- this crash log should be resulted by gdb.

java produced it's own crash reports before.
now it tried to attach with gdb and see, where it hangs.

problem must be somewhere inbetween libc6 (problem appeared in feisty after septemer libc6 update), kernel and java hotspot compiler.

The Hardy Heron Alpha series is currently under development and contains an updated version of the kernel. It would be helpful if you could test the latest Hardy Alpha release: http://www.ubuntu.com/testing . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. We'll keep this report open against the actively developed kernel but against 2.6.22 this will be closed. Thanks.

i will test this issue in virtual machine with latest hardy alpha and post results here.
just need some time to install it.

Finally I managed to install Hardy beta in virtualbox (parallels crashes, qemu has problems with cdrom detection).
Updated all packages to latest. Installed sun-java6-jre package (that's java 1.6.0.05). Copied existing eclipse and code, which I work on, there.
I tried to do all actions, which lead to java hang in Gutsy -- works ok, no hangs.

So, I will repeat all tests again, after update to Hardy release. Should be no problems. If I get something, I will write about it. Otherwise, bug might be closed.

Just reproduced hang-and-crash in hardy release with openjdk.

[Dmitriy Geels (dmig)]

Also reproducible with sun java runtime.

[Matthias Klose (doko)]

- please recheck with openjdk-6 6b11-2ubuntu2 from hardy-proposed
- if still reproducible, please describe what you are doing, which code you run, and provide detailed steps how to reproduce the problem

[Matt Zimmerman (mdz)]

I see no indication that there is a kernel bug involved here, so invalidating this task. The bug remains open on openjdk-6.

Bug isn't reproducible in Intrepid both 32/64 bit kernels so, I suppose, it may be closed.
