Moneydance, a shareware finance manager that I once evaluated (http://www.seanreilly.com), seems to run ok. If you really want to invest the time, you might go to togethersoft.com and download their product. They will send you an evaluation license as soon as you download the product, without any further request. But it's a big application, and you won't have any use for it unless you develop a large-scale JAVA application. -- Regards, Georg. -- Who in the world needs 2000 Windows?

Linux JDK 1.3 and hotspot (native threads)
I remember some reports of success running Linux JAVA with native threads on -current. I've tried several times myself, and can't get it to work. The Linux JDK 1.3 (SUN's version) runs fine on -current as well as 4.x as long as I use the classic VM. This version doesn't use native Linux threads. In order to get real performance I would like to run either the SUN JDK with -hotspot, or the IBM 1.3 JVM. Both of these use native linux threads. With a recent -current I can successfully execute small JAVA test programs, but when I start a real application (e.g. Together from togethersoft.com), it fails with a core dump. The SUN JDK 1.3 gives # # HotSpot Virtual Machine Error, Unexpected Signal 11 # Please report this error at # http://java.sun.com/cgi-bin/bugreport.cgi # # Error ID: 4F533F4C494E55580E43505005BC # # Problematic Thread: prio=671556272 tid=0x804f790 nid=0x2940 runnable # and the IBM JDK 1.3 dies with a similar message. Is anybody successfully using a Linux JVM with native threads on -current? Are there any pathes that you needed to apply? -- Regards, Georg. -- Who in the world needs 2000 Windows?
