Fwd: Temporarily store/restore the current configuration

Hello,

I've been looking at a seemingly simple problem I can't figure out the
solution for - hope it's something you've encountered before.

I have test code that recursively calls certain routines
which emit quite a bit of logging to the console. I'd like to
temporarily switch the logging configuration to one that is less chatty, but
restore the previous configuration afterward (as if nothing changed). Everything
is single-threaded.

I looked at the LoggerContext and its reconfigure(Configuration) and
setConfiguration(Configuration) methods, thinking something like this
would work:

var ctx = (LoggerContext) LogManager.getContext(false);
var current = ctx.getConfiguration();
try {
  ctx.setConfiguration(myQuietConfiguration);
  otherCode();
} finally {
  ctx.setConfiguration(current);
}

But it doesn't. Neither with reconfigure nor with setConfiguration.
The root logger's appenders are never reattached properly.

I wonder what I'm missing here. I've tried several other avenues but I
will spare you the code as none of them worked properly. Any help or pointers
would be greatly appreciated.
