| 36 | * To run this test do this: |
| 37 | * runregress -no InstancesTest <cmd line options> |
| 38 | * |
| 39 | * where <cmd line options> are the options to be used to |
| 40 | * launch the debuggee, with the classname prefixed with @@. |
| 41 | * For example, this would run java2d demo as the debuggee: |
| 42 | * runregress -no InstancesTest -classpath |
| 43 | * $jdkDir/demo/jfc/Java2D/Java2Demo.jar \ |
| 44 | * -client @@java2d.Java2Demo |
| 45 | * |
| 46 | * In this mode, the specified debuggee is launched in debug mode, |
| 47 | * the debugger waits 20 secs, and then connects to the debuggee, suspends |
| 48 | * it, and 'debugs' it. |
| 49 | * |
| 50 | * If <cmd line options> is not specified, then the InstancesTarg class below |
| 51 | * is run as the debuggee. |
