Description

Error occures in groovy-1.0-RC-02, it did'nt occure in JSR6

When calling 'groovy SuperError.groovy' I get the error:
Caught: java.lang.VerifyError: (class: B, method: m signature: (Ljava/lang/Object;)V) Inconsistent stack height 1 != 0
In the method call super.m(p1, 'called from B') the super keyword is not necessary, but it should'nt result in an error.

Here is the code:
----------------------------------------
// SuperError.groovy
class SuperError extends GroovyTestCase {
static void testSuperError()

{ new B().m('Call B.m') }

}

class A {
void m(p1)

{ println 'A.m with parameter: ' + p1 }

void m(p1, p2)

{ println 'A.m with parameters: ' + p1 + ', ' + p2 }

}

class B extends A {
void m(p1)

{ if (p1) super.m(p1, 'called from B') /* This works (without if): super.m(p1, 'called from B') And this works too (without super) if (p1) m(p1, 'called from B') */ }

}
