How are you injecting the latest meth.jar here? I don't see it in the command line. If I run the 7052219 jvm with b145 then it does pass but if I add in meth.jar then I see a crash with WrongMethodTypeException. I think there are still some bugs with throwing these and maybe the very latest JDK changes are throwing it in cases where we wouldn't before. I just reproduced a similar crash when running the very latest JCK tests that I'm investigating as well. The stack trace at the failing point in the jruby case is this: 1 - frame( sp=0xfc64e0c8, unextended_sp=0xfc64e0d0, fp=0xfc64e0d0, pc=0xf978d5cc) java.lang.invoke.MethodHandle.invokeExact 2 - frame( sp=0xfc64e0c8, unextended_sp=0xfc64e0d0, fp=0xfc64e0d0, pc=0xf978d5cc) never.tmp.indy_minus_crasher.date.format.method__4$RUBY$method_missing(/never/tmp/indy-crasher/date/format.rb:121) 3 - frame( sp=0xfc64e0c8, unextended_sp=0xfc64e0d0, fp=0xfc64e0d0, pc=0xf978d5cc) never$tmp$indy_minus_crasher$date$format$method__4$RUBY$method_missing.call(never$tmp$indy_minus_crasher$date$format$method__4$RUBY$method_missing:65\ 535) 4 - frame( sp=0xfc64e0c8, unextended_sp=0xfc64e0d0, fp=0xfc64e0d0, pc=0xf978d5cc) org.jruby.javasupport.util.RuntimeHelpers$MethodMissingMethod.call(RuntimeHelpers.java:497) 5 - frame( sp=0xfc64e160, unextended_sp=0xfc64e160, fp=0xfc64e1bc, pc=0xf9403133) org.jruby.internal.runtime.methods.DynamicMethod.call(DynamicMethod.java:213) 6 - frame( sp=0xfc64e1c4, unextended_sp=0xfc64e1c4, fp=0xfc64e200, pc=0xf9403133) org.jruby.runtime.invokedynamic.InvokeDynamicSupport.callMethodMissing(InvokeDynamicSupport.java:1820) 7 - frame( sp=0xfc64e208, unextended_sp=0xfc64e208, fp=0xfc64e240, pc=0xf9403133) org.jruby.runtime.invokedynamic.InvokeDynamicSupport.invocationFallback(InvokeDynamicSupport.java:455) 8 - frame( sp=0xfc64e248, unextended_sp=0xfc64e258, fp=0xfc64e28c, pc=0xf94036b1) never.tmp.indy_minus_crasher.date.format.method__40$RUBY$_parse(/never/tmp/indy-crasher/date/format.rb:1035) And the exception message would have been "WrongMethodTypeException: (Z)Ljava/lang/invoke/MethodHandle; cannot be called as (Z)Ljava/lang/Object;" It looks like it's part of some selectAlternative code. I don't know if there's enough there for you to understand what it's complaining about. The underlying problem is that we're aren't throwing the WMT correctly when the caller is compiled and bad things occur as a result. tom > > Transform time : 101 > > Can you confirm that? > > -- Christian > >> >> On Wed, Jun 15, 2011 at 7:38 AM, Christian Thalinger >> <christian.thalin...@oracle.com> wrote: >>> On Jun 15, 2011, at 6:09 AM, Charles Oliver Nutter wrote: >>>> Still crashing!
