Hi Jürgen?
Since the log4j upgrade requirement was announced I have been trying unsuccessfully to upgrade the gateway on the pi3b. I am going from 978 -> 981. I'm following the same steps I did before per Scott (MochaSatin) advice from above. Unfortunately, I'm seeing some JavaFX errors in the launcher logs as noted in another post.?
I'm using the default (default-jre) package from apt which appears to include OpenJDK-11 from the official raspbian/debian repository. I tried installing OpenJFX from APT as well, but there was no change in behavior in 981.?
I noticed you are saying to use the 64 Bit Oracle Java. Can you confirm how you are installing it and that you can use the 64 Bit Oracle Java on the Pi? My understanding is that the Pi OS is 32bit, so I'm confused why or how you would be installing the 64 bit version. Thanks
