Sorry twisti, I can't help elucidate this one any further as yet, but just 
thought I'd chime in with a 'me too' as I've also seen this in trying to 
build HotSpot -- it's where I got stuck IIRC.

Cheers,

Do you have more context? (pun intended)

The part of the stacktrace you posted just pushes a 'null' context
reference around which is dereferenced and generates the
NullPointerException in the end. We need to see more to know why context
is null in the first place.

Hi Chris!

I'm sending this directly to you, as you said you don't get these mails.

I've tried your test program and, yes, it works.  But only with
jvmti.xsl, it fails with jvmtiEnter.xsl, though.  You should try that
one...

Thanks for that. A fix is in HEAD.
