Eric Milles closed GROOVY-8265.
-------------------------------
Resolution: Fixed
> If CompileStatic is used, metaClass variable shadowing triggers exception
> when invoking closures

> Key: GROOVY-8265
> URL: https://issues.apache.org/jira/browse/GROOVY-8265
> Project: Groovy
> Issue Type: Bug
> Components: groovy-runtime, Static compilation
> Affects Versions: 2.4.12
> Reporter: Sergio Nalin
> Priority: Minor
> Attachments: Bug.groovy

> See the small attached example class.
> Problem arises if you define a local variable and name it "metaClass", then
> call a closure that accepts some parameters like map.each { key, value -> ...
> }.
> When the code gets to Closure.call(Object... args) it executes:
> return (V) getMetaClass().invokeMethod(this,"doCall",args);
> only now getMetaClass() returns the shadowed metaClass variable, not the
> Closure's metaClass and an exception is thrown if the class that the external
> metaClass belongs to does not define a doCall(args) method.
> This seems to be happening only with @CompileStatic
> Renaming the local variable from metaClass to anything else works around the
> problem.
