[OpenJDK Rasterizer] Segfault in marlin code for Java 9 ea100

[Mike Bremford]

Hi All


I was steered to this list after initially posting here:
https://community.oracle.com/message/13632163


We've been doing some initial testing of our product with Java 9 (build
9-ea+100-2016-01-06-195905.javare.4235.nc on multi-core Xeon running Linux)
and managed to get a consistent segfault out of it.

I have narrowed it down to a self-contained test case which you can run -
there's a lot going on under the hood in our Jar which I cant supply the
source for, but I imagine for a SEGV the source won't make much difference.
The testcase is 3.2MB, if anyone wants it please drop me an email directly
or let me know and I'll post it to this list.


Cheers... Mike
