| /* |
| Test that the RMI connector client can handle a URL of the form |
| where the serialized RMIServer stub is encoded directly in the URL, |
| when the class of that stub is known to the supplied |
| DEFAULT_CLASS_LOADER but not to the calling code's class loader. |
| This is an unusual usage, and is not explicitly specified in the JMX |
| Remote API, but it is potentially useful where client and server |
| agree to a code base for mutant stubs (that e.g. use a different |
| protocol or include debugging or optimization). |
| |
| We make an RMI connector server by giving it an instance of an |
| RMIJRMPServerImpl subclass that manufactures mutant stubs. These |
| stubs are known to a special loader (mutantLoader) but not to this |
| test's loader. We set up the client's default loader to |
| mutantLoader, and check that it can deserialize the stub containing |
| the mutant stub. |
| |
| This test incidentally creates the connector server as an MBean |
| rather than using the JMXConnectorServerFactory, just because I'm |
| not sure we have coverage of that elsewhere. |
