The HotSpot compiler uses OSR (on stack routines) to deal with certain exception situations. If that doesn't mean that it puts a routine on a stack for execution, then I don't know what does. Many modern language runtimes use these kind of conventions, so it's bound to create problems with other systems. bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
