JVM Internal Error when running simple lambda

[Rémi Forax]

Hi Tomasz,
I was able to reproduce the bug,
it only appear with a fastdebug VM not with a product VM.

So it's perhaps just a grumpy assert :)

PS: I've CC to mlvm and put the two necessary classes to reproduce the 
bug as attachment.

[forax at localhost src]$ /usr/jdk/fastdebug/jdk1.7.0/fastdebug/bin/java 
-XX:+UnlockExperimentalVMOptions -XX:+EnableInvokeDynamic SimpleExtractor
VM option '+UnlockExperimentalVMOptions'
VM option '+EnableInvokeDynamic'
