/* @test

 * @bug 4889342

 * @summary This test verifies that when a primitive boolean value is

 * passed by a dynamic proxy class to an invocation handler, it is

 * boxed as one of the canonical Boolean instances (Boolean.TRUE or

 * Boolean.FALSE).  This test also exercises a dynamic proxy class's

 * boxing of all primitive types.
