Good point. I believe my [original patch](https://github.com/openjdk/jdk/compare/master...68cccbf18ab1dea51e3e673523e77a19cc221b82) which adds a `protected Runnable decorateExecution(Runnable)` method instead did not have this issue, so we could just revert to that approach.

Or there is the other approach (previously mentioned) which adds `executionStart()` and `executionFinish()` methods and should also be safe.

@lahodaj what's your opinion here?

Thanks.
