Description

Cannot compile statements like SomeClass.<Integer>create(). Example code:

Test.groovy

class Test<E> {
        E someVariable;

        protected Test() {
        }

        public static <E> Test<E> create() {
                return new Test<E>();
        }

        public static void main(String[] args) {
                Test<Integer> t = Test.<Integer>create();
        }
}

The error is:

$ groovy Test.groovy
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/home/aless/Test.groovy: 12: Unknown type: TYPE_ARGUMENTS at line: 12 column: 26. File: /home/aless/Test.groovy @ line 12, column 26.
                Test<Integer> t = Test.<Integer>create();
                            ^

1 error

Exactly the same file (with a .java extension) compiles with javac.
