| /* @test |
| @bug 4147599 4478150 |
| @summary In 1.2beta4-I ClassLoader loaded classes can not link |
| against application classes. |
| */ |
| |
| /* |
| * We are trying to test that certain methods of ClassLoader look at the same |
| * paths as they did in 1.1. To run this test on 1.1, you will have to pass |
| * "-1.1" as option on the command line. |
| * |
| * The required files are: |
| * |
| * - Loader.java (a 1.1 style class loader) |
| * - Loadee.java (source for a class that refers to Loader) |
| * - Loadee.classfile (to test findSystemClass) |
| * - Loadee.resource (to test getSystemResource) |
| * - java/lang/Object.class (to test getSystemResources) |
| * |
| * The extension ".classfile" is so the class file is not seen by any loader |
| * other than Loader. If you need to make any changes you will have to |
| * compile Loadee.java and rename Loadee.class to Loadee.classfile. |
