| * @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. |
