Description

When by error I created a class with two exact same methods, the class was compiled, however, when run, a ClassFormatError was thrown:

Caught: java.lang.ClassFormatError: GroovyShellSamplesTest (Repetitive method name/signature)

A simple class like that will yield the error:

class FooFooTest extends GroovyTestCase {
void foo() {}
void foo() {}
}

Ideally, we should get a nice error message when compiling the class
