Nashorn fails to evaluate compiled script

[A. Sundararajan]

Hi,

Do you have this changeset from 
http://hg.openjdk.java.net/nashorn/jdk8/nashorn ?

summary:     8024973: Using a different ScriptContext with a 
CompiledScript results in ScriptException

I've added a simplified test in the repo. "ant clean test" should pass 
everything. ScriptEngine.compileAndEvalInDiffContextTest is the test 
added. If that one does not cover your application, then I'd need more 
info on your application or another simplified test case demonstrating 
your particular scenario.

BTW, it is better is to avoid changing ENGINE_SCOPE bindings -- i.e., 
using one global (ENGINE_SCOPE) for compilation and running the code for 
another global object for 'eval' could be the reason. In any case, a 
simpler test case would be better.

Thanks
-Sundar
