ADDITIONAL OS VERSION INFORMATION :
Darwin crab.lan 15.3.0 Darwin Kernel Version 15.3.0: Thu Dec 10 18:40:58 PST 2015; root:xnu-3248.30.4~1/RELEASE_X86_64 x86_64

A DESCRIPTION OF THE PROBLEM :
We've observed a change in behaviour between 1.8.0_71 and 1.8.0_72, where we now see a ReferenceError.

Reproduction code is available.

REGRESSION. Last worked in version 8u71

ADDITIONAL REGRESSION INFORMATION:
See https://github.com/makuk66/eval-script-repro, which runs code first with _71 which works, and then with _72, which doesn't.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Clone https://github.com/makuk66/eval-script-repro
Edit run.sh to point to set the JAVA_HOME to point at your copies
Execute ./run.sh
Observe the output is per the README, demonstrating success for _71 and then failure for _72.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expected _72 to behave in the same way as _71
ACTUAL -
_72 gets a ReferenceError
