* @ 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 .
