| 26 | @summary In 1.2beta4-I ClassLoader loaded classes can not link |
| 27 | against application classes. |
| 28 | */ |

| 30 | /* |
| 31 | * We are trying to test that certain methods of ClassLoader look at the same |
| 32 | * paths as they did in 1.1. To run this test on 1.1, you will have to pass |
| 33 | * "-1.1" as option on the command line. |
| 34 | * |
| 35 | * The required files are: |
| 36 | * |
| 37 | * - Loader.java (a 1.1 style class loader) |
| 38 | * - Loadee.java (source for a class that refers to Loader) |
| 39 | * - Loadee.classfile (to test findSystemClass) |
| 40 | * - Loadee.resource (to test getSystemResource) |
| 41 | * - java/lang/Object.class (to test getSystemResources) |
| 42 | * |
| 43 | * The extension ".classfile" is so the class file is not seen by any loader |
| 44 | * other than Loader. If you need to make any changes you will have to |
| 45 | * compile Loadee.java and rename Loadee.class to Loadee.classfile. |
