STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I don't know how to reproduce this bug since javac doesn't give much information about it. I could have given you exactly the line where javac fails if you tell me how to make javac tell me.


REPRODUCIBILITY :
This bug can be reproduced always.

The fix for JDK-8029569 was incomplete and this bug is proving that.

Release team: Approved for deferral. Deferring this to 8u20 since 9 is too far out (unless this is a fix that can only be done in a major release, if so please move it to 9)
