With JEP 491 integrated it meant that the java.io classes could be changed back to use synchronized.  Yes, we could do some cleanup in Throwable too. Changing PrintStreamOrWriter to be an interface should be fine but the rest of these changes in this PR doesn't seem necessary. As others have already asked, I think it would be useful to understand what issue you are running into and why you want to change this code.

@AlanBateman I have modified it to use interface + record. Is this what you want?
