I've screwed up the Java package on my machine, and now the system can't see/run java. Background: In order to use packages NetRexx and NetRexx-Pipelines, which until recently depended on Java 8, I had both Java 8 and Java 11 installed, with update-alternatives mediating the two. Now the NetRexx products have been upgraded to work with Java >8, so I didn't need the Java 8 any more. I deleted that, but I'm guessing that update-alternatives wasn't notified. I removed the entries from its "database", but that hasn't helped. Poking around, I see various things like aliases defined in /etc, that refer to java, but don't have comments, etc. tying them to one or the other of the packages. I'm thinking that I need to delete the NetRexx components (easy), then Java 11, then reinstall Java and then NetRexx.

I tried to use YaST sw_single to delete the two Java 11 packages, but bizarrely, it tries to install them instead of removing them. Help! Leslie -- openSUSE Leap 15.2 x86_64
