// Extended regression test for the PR 179.
//
// This tests the ".class" language syntax, initialization behaviour for 
// Class.isInstance() and Class.isAssignableFrom(), and isAssignableFrom()
// functionality in the event that an interface argument that is not 
// implemented by any loaded class is given.
// Note that the desired output changed from 1.4 to 1.5.
