The production/non-debug builds were crashing last night, but I reduced the optimization level to -O0 and progressively got it to run more reliably. At -O0 the HotSpot production version runs reliably for the Java2D demo. I'm turning off specific optimization options incrementally as I increase the global level of optimization to find what's blowing things up. With the no optimizations at -O0, I get within 50 percent of the native Linux JDK in speed running Java2D. This is really encouraging. bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-java" in the body of the message
