Description

For this code:

class Foo {
    static interface A{}
    static interface B{} // (1)
    static class Inner<X> {}
    static Inner<A> method() {} // (2)
}

println new Foo()

This error is received:

java.lang.ClassFormatError: Duplicate entry in InnerClasses in class file Foo

Removing either the declaration of B at (1) or the Generics attribute <A> on the type Inner at (2) will avoid the error.
