Integration

Hi,

we experience crashes of our Jenkins after upgrading to JRockit R28.2.0-79-14677 from R28.1.

Now:
java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11)
Oracle JRockit(R) (build R28.2.0-79-146777-1.6.0_29-20111005-1807-linux-x86_64, compiled mode)

Before:
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Oracle JRockit(R) (build R28.1.0-123-138454-1.6.0_20-20101014-1350-linux-x86_64, compiled mode)


Maybe this dump file already helps, I'll try to get a .core file too. I noticed there has been a similar issue with R28.0.1 (Oracle support [ID 1295504.1] / Bug 10418780) but it should have been fixed in R28.1.1. From the dump-file we have no stack overflow and different signal info (Signal info : si_signo=11, si_code=1 si_addr=0x2aaaf318a910) from the one in the bug description.
