Description

The following code compiles and runs in Groovy 1.8.6...

def a= new java.util<Integer>.ArrayList<ArrayList<Integer>>()

The parser allows a generic type after each name in the fully-qualified class name. The generic type should only be after the final name.

The relevant part of the Antlr parser that needs fixing is:

typeParameters: LT typeParameter (COMMA typeParameter)* (typeArgumentsOrParametersEnd)?
typeParameter: IDENT (typeParameterBounds)?
typeParameterBounds: "extends" classOrInterfaceType (BAND! classOrInterfaceType)*
