@dean-long,  there is null check in predicate code:
https://github.com/openjdk/jdk/blob/master/src/hotspot/share/opto/callGenerator.cpp#L1268

This is first time we use `PreserveReexecuteState` for an intrinsic with predicate. But I am actually not sure if the failure I see is caused by this changes or existing bug. But it causes concern.

@smita-kamath yes, please prepare new changes with stack allocation and I will test it.
