/* This is the core of the test. Given the MXBean interface c, we make an MXBean object that implements that interface by constructing a dynamic proxy. If the interface defines an attribute Foo (with getFoo and setFoo methods), then it must also contain a field (constant) Foo of the same type, and a field (constant) FooType that is an OpenType. The field Foo is a reference value for this case. We check that the attribute does indeed have the given OpenType. The dynamically-created MXBean will return the reference value from the getFoo() method, and we check that that value survives the mapping to open values and back when the attribute is accessed through an MXBean proxy. The MXBean will also check in its setFoo method that the value being set is equal to the reference value, which tests that the mapping and unmapping also works in the other direction. The interface should define an operation opFoo with two parameters and a return value all of the same type as the attribute. The MXBean will check that the two parameters are equal to the reference value, and will return that value. The test checks that calling the operation through an MXBean proxy returns the reference value, again after mapping to and back from open values.
If any field (constant) in the MXBean interface has a name that ends with ObjectName, say FooObjectName, then its value must be a String containing an ObjectName value. There must be a field (constant) called Foo that is a valid MXBean, and that MXBean will be registered in the MBean Server with the given name before the test starts. This enables us to test that inter-MXBean references are correctly converted to ObjectNames and back.
