Description

The Groovy parser currently does not understand the Java syntax needed to instantiate a Java inner class. Groovy does not allow the declaration of inner classes but it must be able to work with inner classes defined in Java. The issue does not affect top-level nested classes only inner classes, i.e. instantiation of classes that have to be instantiated in the context of an existing object. So given the Java class:

public class X {
public class Y

{ int z ; }

}

the Groovy script:

def x = new X ( )
def y = x.new Y ( )

should either work or there needs to be some new syntax in Groovy to achieve the goal. Currently the result of executing this script is:

./test.groovy: 4: unexpected token: new @ line 4, column 11.
def y = x.new Y ( )
^

1 Error

which has to be considered wrong I think.
