in practice this means you will be screwed if your code is first called in a manner that will hit the reduced stack frame limit before the JIT had a chance to compile code.

So not sure why you say here "more important" bye Jochen -- Jochen "blackdrag" Theodorou - Groovy Project Tech Lead blog: http://blackdragsview.blogspot.com/ german groovy discussion newsgroup: de.comp.lang.misc For Groovy programming sources visit http://groovy-lang.org _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
