@thwaller looking at the slides from https://static.rainfocus.com/oracle/oow1...01v8uS.pdf you may get a feeling how Java changed between J8 and J11 -> and these are all things where we have no influence

@mlaggner - Sorry for the late reply, and thank you for your replies regarding the issue. I completely agree this is a Java issue and not a tMM issue, and in saying that, I greatly appreciate your efforts to still help. I believe I can show blame on an issue with Java + Ubuntu on this. You will recall a conversation where I had what appeared to be Java 11 packages installed, yet they were actually Java 10 packages. I believe it was you who pointed this out with some detail. So once the Java actually was Java 11 packages, that is when I had first started reporting strange things. This font issue was the last one reported. I have found a fix, although I hate to even call it a fix, but the issue is resolved.

I am being overly descriptive as it might help someone else, and you may have interest as well.
1) in "/home/user/.java/fonts/11.0.2" I deleted "fcinfo-xxxxxxxx.properties"
2) in "/home/user/.java/fonts/10.0.2" I copied "fcinfo-xxxxxxxx.properties" and pasted to "/home/user/.java/fonts/11.0.2"
Done.

I am sure there is a more logical explanation or even a better way to do this, but those are the exact steps I took to resolve. This allows me to now run tMM with no errors with the following:
openjdk 11.0.2 2019-01-15
OpenJDK Runtime Environment (build 11.0.2+9-Ubuntu-3ubuntu118.04.3)
OpenJDK 64-Bit Server VM (build 11.0.2+9-Ubuntu-3ubuntu118.04.3, mixed mode, sharing)

I am far from a Java person, but it appears as though something got mucked with the upgrade from 10 to 11. If my assumptions are wrong, anyone feel free to shed some light on what actually happened here. All I have as fact is the exact steps I took and the results.
