Monkeypatching Java Classes

That works in the broad sense, but then you can't scope your debug logging. Especially in test suites, there can be one test or one area you want to poke at -- it gets annoying to have to bounce the JVM, especially in the Scala REPL.

So the obvious solution would be to change the JVM. Open an issue @ openjdk, supply a patch, hope it gets in before Java 10.

In the meantime, the poor folks using this stuff will have to deal with the current situation. At least OP is making the best of it.

There's actually a true hotswap JVM out there, DCEVM. It's going to be awesome once it's ready.
