Kevin, Just as an aside, if you (or anyone else here) does find yourself needing to escalate bugs with printing APIs to the JDK-level, please feel free to send me a DM. Here's some examples, authored by a commercial JDK-support provider that I work closely with. I say this out of empathy (no sponsorship) as it took me a long time to get someone to help with these things. :)
