Description

If a groovy class overrides a final method then groovyc will compile it fine, but the .class file generated will be invalid: -

Base.java
public class Base {
final int getCount()

{ return 1; }

}

MyBase.groovy
class MyBase extends Base {
int getCount()

{ return 2; }

}

These will both compile with groovyc without error. It's only when you try to compile: -

MyBaseTest.groovy
class MyBaseTest extends GroovyTestCase {
void testBasic()

{ b = new MyBase() assert b.count == 2 }

}

... that groovyc throws a MissingClassException. Running javap on MyBase.class fails (it exposes a bug in javap that I think only happens for invalid class files).
