I've closed [JDK-8203035](https://bugs.openjdk.org/browse/JDK-8203035) as Won't Fix; see comments there. Based on that analysis I recommend that we not proceed with this PR.

Briefly, I'd recommend that you implement your own logic for reducing logging messages based on "duplicate" exceptions. The logic for detecting duplicate exceptions is most likely application-specific and thus probably doesn't belong in the JDK.
