Long parameter list crashes JVM on x86

[Maurizio Cimadamore]

Very interesting - thanks for the report.

 From the title of your email, I was expecting a single downcall with 
lots and lots of native parameters, but your example seems to be 
crashing while building the downcall method handle, which you are then 
not even calling.

We will take a look. I've filed this:

https://bugs.openjdk.org/browse/JDK-8338123

Cheers
Maurizio
