| * and checks up the following assertion: <br> |
| * "If the bytes do not represent a valid class, <code>ClassFormatError</code> |
| * will be thrown." |
| * |
| * The test consists of the following files: <br> |
| * <code>redefineclasses029.java</code> - debugger <br> |
| * <code>redefineclasses029a.java</code> - initial debuggee <br> |
| * |
| * This test creates byte code, that has zero-length, and tries it |
| * to redefine the debugee. The test expects <code>ClassFormatError</code> exception. |
| * When <code>canRedefineClasses()</code> is <code>false</code>, the test is |
| * considered as passed and completes it's execution. |
