It's always easier to create something new that meets exactly your own needs,
with no requirement to be compatible with anything. But if you want Oracle to
support a new standard API for logging, I think you're going to need to convince
us that the existing standard API for logging can't be improved to meet your needs.

"I don't like it" is not a reason.

"It's too hard" is not a reason.

"No one uses it" is not a reason.

"That's not the way I would've done it" is not a reason.

The existing API wasn't created in a vacuum - it was created by a group of
experts from many companies who had experience with logging. Maybe we've
learned a lot about logging since then. If so, convince us.

My impression is that most of the existing logging frameworks were created by
someone who wanted something more or different out of logging than they could
get with java.util.logging, and since they couldn't change java.util.logging
they built something alongside it or on top of it. Well, what if you *could*
change java.util.logging? Could you make it do what you think it should do?

Either way, the place to make your argument is probably in the OpenJDK project.
