SchemaSpy: Error: java.lang.UnsupportedClassVersionError

[babsvoneuw]

When running this command: java -jar schemaspy-6.2.4.jar -vizjs we got the following error:
ERROR: Caused by: java.lang.UnsupportedClassVersionError: org/openjdk/nashorn/api/scripting/NashornScriptEngineFactory 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 52.0
the java-jre-version is: openjdk version "1.8.0_345"
I didn't found a way to change the java-jre-version - what options do I have to make this work?

Expected Behavior

schemaspy should also work with jre 1.8

Current Behavior

schemaspy doesn't work with jre 1.8

Possible Solution

Steps to Reproduce (for bugs)

  java -jar schemaspy-6.2.4.jar -vizjs

• Operating System and version (e.g. Windows 10): windows
• Java version:openjdk version "1.8.0_345"

We must have added a Java 11 dependency into 6.2.4 which is bad. The solution would be to use java 11 or 17 if possible.

We have since moved on to java 17, and next release will require java 17. It might have sneaked thru, due to a requirement from our quality tool that requires java 11 to run. So SchemaSpy is compiled for java 8, but the dependency for JavaScript that was added and it was compiled for java 11.

Looks like this affect all version 6.2.*
