EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No crash

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
 I see it's fixed in JDK 10 which is great. Unfortunately that's not going to help users experiencing this in the field for years.

Can we please get this back ported to JRE 8?

We get multiple reports of this daily for our software. It's just a null pointer check, so low risk?
