Bug report: AtomicInteger is converted to a Number when returned from function

[A. Sundararajan]

Yes, this is a bug with 8u-dev and 9-dev - but not reproduced with 8u20 
binary. With 8u-dev and 9-dev, the scripts runs fine with 
--optimistic-types set to false. I've filed a bug:

https://bugs.openjdk.java.net/browse/JDK-8056129

Thanks for reporting this issue.

Thanks
-Sundar
