Missing error for class implementing package

[Jesper Öqvist]

ExtendJ 8.0.1-161-g2081568 Java SE 8

A class may not implement a package, however the following test case gives no error when compiled with ExtendJ:

// Package name used as a typename.
// A class may not implement a package.
// .result: COMPILE_FAIL
package org.extendj;

public class Test implements org.extendj {
}
