Just an update on the broken IBM JDK issue. I've been working with the Linux emulation people, and we've narrowed the problem down to a bug somewhere in the kernel -- most likely in modify_ldt(). Here's what we've found: * modify_ldt() is returning an illegal value (the selector index) when called with func 0x11. * The main JVM thread is receiving a SIGSEGV immediately thereafter. * An endless stream of kernel trap 26 (segment-not-present) errors is recorded in /var/log/messages. * The exact same sequence of calls does not fail on Linux. Unfortunately, I have not been able to capture any core dumps since (on my system) the process hangs and does not crash. If anybody out there does have any dumps, please email them to me. -- Milo Hyson CyberLife Labs To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-java" in the body of the message
