When I upgraded my kernel from gentoo-sources 2.4.22-r7 to 2.4.25 I was unable to run jedit or ant 1.5.4-r1 due to the VM core dumping. The JDK seemed to be able to compile and run very simple programs, but anything at all complex would kill it. I tried reverting to my old kernel, and my java worked perfectly. I tried unmerging ant and sun-jdk under the new kernel, then re-emerging them and the problem occurred again. Reproducible: Always Steps to Reproduce: Under a gentoo-sources 2.4.25 kernel: 1. emerge sun-jdk 2. emerge dev-java/ant 3. core dump Actual Results: Unexpected Signal : 11 occurred at PC=0x462B8236 Function=[Unknown.] Library=(N/A) NOTE: We are unable to locate the function name symbol for the error just occurred.

I too have this same problem. I've been discussing it on the gentoo forums, I did not think it was a kernel issue (others suggested it might be a glibc issue, but this seems unlikely now that I have tried using the same glibc as those who have it working). The forum topic is at: http://forums.gentoo.org/viewtopic.php?t=153928
I have just upgraded my kernel to development-sources-2.6.5-rc2, and the problem has now disappeared. So, the problem is definitely something to do with the gentoo-sources-2.4.25 kernel.
Created attachment 28391 [details] kernel config from original bug submitter This is the configuration of my gentoo-sources 2.4.25 kernel that makes Java core. Sorry for not including it in the original bug report. Hopefully it's useful. I should add that I experienced identical core dumps on two separate machines: a Dell Latitude CPx/J and a Pentium 233/MMX with minimal additional hardware. It seems from the forums that many people are having the same trouble.
can you try with grsecurity disabled?
I just installed a new gentoo-sources 2.4.25 kernel with grsec disabled on my laptop, and Ant seems to work fine now. That seems to be the problem, then.
anything in dmesg after this happens?
Just this was in my dmesg after ant core dumped, in a 2.4.25 kernel with grsec set to medium: grsec: signal 11 sent to (java:5288) UID(1000) EUID(1000), parent (ant:1837) UID(1000) EUID(1000) grsec: signal 6 sent to (java:5288) UID(1000) EUID(1000), parent (ant:1837) UID(1000) EUID(1000)
You need to chpax/paxctl your java bins. This kinda falls under a know issue with java* If your using EI_PAX flags then try chpax -zsp /path/to/java/bin/* If you compiled with PT_PAX support then try paxctl -sp /path/to/java/bins/* 99% chance this bug can be closed as INVALID
please follow Solars (grsecurity gentoo maintainer) recommendations
