/** |

* Do nothing when first triggered; then, in the final round, generate a |
| 32 |
* new type that is annotated with {@link FinalRoundTestTrigger}. |
| 33 |
* Used to verify that a new type generated in the final round does not get |
| 34 |
* annotations processed, but does get compiled. The JSR269 spec is somewhat |
| 35 |
* vague about whether it should be possible to generate a new type during |
| 36 |
* the final round (since the final round does not happen until after a |
| 37 |
* round in which no new types are generated); but apparently javac behaves |
| 38 |
* this way. |
