| /** |
| * Invokes RMIClassLoader.loadProxyClass() to load a proxy class with |
| * multiple interfaces using using RMI class unmarshalling. Test is |
| * composed of cases which each unmarshal a proxy class in a |
| * different environment. All of the cases create needed class |
| * loaders, load appropriate interfaces, create a proxy class that |
| * implements those interfaces, create a marshalled object from that |
| * proxy class, and finally call .get() on that object. Get of the |
| * object should pass in some cases and fail in others. |
| * |
| * 1. Nonpublic interface loaded from the parent of the First |
| * Non-Null class Loader on the execution stack (FNNL). Public |
| * interface loaded from grandparent of FNNL parent. Proxy class must |
| * be defined in non-null FNNL parent. Should succeed. |
| * |
| * 2. Nonpublic interface (java.util.zip.ZipConstants) and public |
| * interface (java.util.zip.CheckSum) loaded from bootclasspath, |
| * proxy class defined in null/boot class loader. Should succeed. |
| * |
| * 3. Public interface classes loaded in FNNL are also available in |
| * RMI loader parent. FNNL is grandparent of RMI loader. Proxy class |
| * must be defined in RMI class loader. Should succeed. public |
| * interface must be defined in FNNL. |
| * |
| * 4. Non-public interfaces have multiple class loaders. Should fail |
| * with a LinkageError. |
| * |
| * 5. Interface classes loaded from RMI class loader. Proxy class |
| * defined in RMI class loader. |
| * |
| * 6. Not all interfaces classes can be loaded from a single class |
| * loader; should fail with ClassNotFoundException. All interface |
| * classes will exist (but not all interfaces will be available from |
| * one class loader). |
| * |
| * 7. prove that proxy loader has correct annotation. |
| * |
| * 8. REMIND: may want to add a case where the FNNL is null (This |
| * would be for class unmarshalling in the implemntation of a remote |
| * method invocation). |
