I am not sure this is a compiler bug but it says its a c1 frame, so I will start there. These crashes happen with 11.0.24 builds

We recently upgraded to Renaissance JMH 0.15 after a long time running 0.14.x for promo testing.
These did not crash in the 0.14 versions but there is a big difference in the libraries used in the apps.

We get a crash in a couple of Spark based Renaissance where the top of the stack in hs_err file looks like:
