//  The order of the classes is crucial, the first must be the GroovyTestCase.  Its name doesn't
//  matter it just has to be first.

/**
 * Test class and support to realize the GROOVY-662 test.  There is a difference between
 * improper uses of properties between Groovy defined classes and Java defined classes.  There
 * is no difference between correct uses so this is not a problem just an anti-regression test.
