| /** |
| * This test exercises the JVMTI event <code>NativeMethodBind</code>. |
| * <br>It verifies that binding native method can be redirected during |
| * the event callback.<p> |
| * The test works as follows. An agent part enables the NativeMethodBind |
| * generation. Then the java part invokes the native method |
| * <code>nativeMethod()</code> which leads to the NativeMethodBind generation. |
| * In NativeMethodBind callback incoming address of the nativeMethod() is |
| * changed to the address of another native method |
| * <code>redirNativeMethod()</code>. |
| * Both functions nativeMethod() and redirNativeMethod() count their calls.<br> |
| * In accordance with the spec, the nativeMethod() should not be invoked |
| * and the redirNativeMethod() should be invoked once. |
