FlatLaf not loading

This is extremely bizarre...

Can imaging one possibility where this could happen: FlatLaf 1.1.2 or older is somewhere on classpath.
Older FlatLaf versions do not have setup() methods. They use install() methods.

The class FlatDarkLaf is probably found because otherwise a ClassNotFoundException would be thrown.

You could use

FlatDarkLaf.install();

or

try {
    UIManager.setLookAndFeel( new FlatDarkLaf() );
} catch( Exception ex ) {
    System.err.println( "Failed to initialize LaF" );
}

to avoid this. (with the "risk" that a old FlatLaf version is used if my initial assumption is right)

BTW the "fix" in commit a3abffe probably does not work because NoSuchMethodError is not caught because it is not a subclass of Exception. Better catch java.lang.Throwable or java.lang.Error.

Thank you, this makes sense, but what would cause an older version of FlatLaf to be on the classpath? I package this application with FlatLaf 2.1, so I'm not sure where it would come from...

Also thanks for catching that slip-up :)
