it used to, but right now I can't even run the installer anymore since 
it crashes. Here's some debugger output:

java/lang/Thread.run has no handlers.

it crashes because JNIEnv env is garbled, and an attempt to call 
(*env)->GetStringChars fails since it's 0. Ouch.

The problems seem to have started with Tim's JVMPI patch. Kaffe from Sat 
Jul 26 16:55:40 2003 UTC just crashes after a while when runng the 
jythos-21 installer. The first crash with the same pattern is from Mon 
Jul 28 09:45:05 2003 UTC, since Guihem's patch fixed the first crash. 
Maybe they have an idea what's happening.
