I don't see an issue with what you're doing, though we have been
trying to slowly obsolete ThreadGroup..

For an alternative, see section on "Using ThreadLocal to simplify
debug logging" in Threading Lightly, part 3:


An InheritableThreadLocal would pass the log from parent to child.

I can't think of a great reason to switch to ThreadLocal.
