Cannot Launch VStar on Fedora Linux v.32

I am unable to launch VStar under RedHat Fedora Linux v.32. I'm probably missing something simple here but I've never had a problem before under other Linux variants such as Debian and also OpenBSD and FreeBSD.

First, here is my version of Java that is installed:

[msoukup@krisztina vstar]$ java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (build 1.8.0_242-b08)
OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode

Here is what I get when I try to launch VStar:

[msoukup@krisztina vstar]$ sh VStar.sh
 
Exception: java.lang.NoClassDefFoundError thrown from the UncaughtExceptionHandler in thread "AWT-EventQueue-0"

No VStar window comes up. Again, I've never before had such a problem running VStar, so I'm a bit puzzled. Can anyone point the way to a solution?

VStar on Fedora

Hi Mike

Not sure what's causing the error, but you could try an alternative like Amazon Corretto Java:

VStar Launch Problem: Resolved!

Hi David --

I tried your suggestion. After uninstalling Oracle Java OpenJDK 1.8 I then installed Amazon Corretto Java for Fedora Linux.

This works! VStar fires right up just fine!

 

Many thanks,

Mike
