[Solved] Java Runtime Version Conflict

My system is all up to date. I removed and then re-installed jEdit but this is what I get:

$ jedit
Error: LinkageError occurred while loading main class org.gjt.sp.jedit.jEdit
	java.lang.UnsupportedClassVersionError: org/gjt/sp/jedit/jEdit has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 54.0
$ java -version
openjdk version "10.0.2" 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13)
OpenJDK 64-Bit Server VM (build 10.0.2+13, mixed mode)

I use LibreOffice and that may be the only other Java applications I use, although I'm not sure

Any suggestions how I can get jEdit to run?

Re: [Solved] Java Runtime Version Conflict

You need a newer JVM, i.e. JRE 11 at the least which is the current LTS. 10 is deprecated and shouldn't be actively used for that matter.

Re: [Solved] Java Runtime Version Conflict

I installed and tried selecting JVM 11 and 15 but neither seem to work. After I installed them, I rebooted as well, just to be sure. This is what I see:

[cpnkirk ~]$ archlinux-java status

  java-10-openjdk
  java-11-openjdk (default)

Re: [Solved] Java Runtime Version Conflict

Which packages did you install? You need the jre11-openjdk package for the full runtime. This works fine here.
