I'm running RedHat Linux 6.0, but with an upgraded kernel (2.2.14) and a new glibc (2.1.3), which is what comes with RedHat 6.2. In case it matters, I've also tried the glibc that comes with RedHat 6.1. I'm running JDK 1.2.2 RC4, the latest version available. Running with green threads and no JIT seems to work alright, though I haven't tested it thoroughly. Running with native threads (and no JIT) results in the following: $ java -native -version SIGSEGV 11* segmentation violation si_signo [0]: no signal si_errno [0]: Success si_code [0]: SI_USER [pid: 0, uid: 0] The process runs out of control. The process list involving java looks like this: 30034 pts/6 S 0:00 /usr/local/jdk1.2.2/bin/sparc/native_threads/java -version 30072 pts/6 R 0:49 /usr/local/jdk1.2.2/bin/sparc/native_threads/java -version 30073 pts/6 S 0:00 /usr/local/jdk1.2.2/bin/sparc/native_threads/java -version I've managed to install the hotspot JIT (it took some effort, since it tries to run the JDK with the -native flag during installation), but when I run Java with the JIT on, I get the following error: $ java -green -version HotSpot VM warning: Cannot recognize SPARC version (0x5). Default to V9 # # HotSpot Virtual Machine Error, Unexpected Signal 4 # # Error ID: 4F533F4C494E55580E4350500CC0 FF # I'm not running on a V9 (which is an UltraSparc chip, no?) I'm running on a SparcStation 10, with whatever CPU is in there. Is it safe to assume that hotspot simply does not support the CPU in my machine? I'm running on a Sparcstation 10. Does anyone run a machine with a similar configuration? If anyone does, and nobody knows a solution to this problem, could you send me a note and we could compare configurations, and see what might possibly be different about them that could be causing this?
