Jochen,
Thanks for investigating. I indeed found the jvm bug report:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8019184
I've also confirmed that it's working on jdk 1.8 developer previous fwiw.
Thanks!

it is from the invokedynamic stuff, so no wonder there is no such problem in the \

that speaks imho again for a jvm bug... since invokedynamic I am a bit fast with \
that... but this one looks like a clear bug in MethodHandles#catchException to me. I \
