BlindGuyNW Posted April 2, 2018 Report Share Posted April 2, 2018 I've been trying to use Hero Designer on the latest version of Mac OS, and running into problems with Java. I get the following error when I try and run the program: java.lang.NoClassDefFoundError: com/sun/java/swing/plaf/nimbus/NimbusLookAndFeel. Followed by a stack trace. This seems to be a problem with the latest Java version, but I can't pin down an exact cause. Has anyone else experienced this? Quote Link to comment Share on other sites More sharing options...
Simon Posted April 2, 2018 Report Share Posted April 2, 2018 I build HD under MacOS. Please post the output from "java -version" on your system -- my suspicion is that you're using Apple's implementation of Java rather than the official release through Oracle.

Simon Posted April 2, 2018 Report Share Posted April 2, 2018 I'd recommend grabbing Java directly from Oracle, which is currently at version 8 update 161. It's likely that Apple didn't bother to implement some of the UI/LNF packages in their version (which is an issue, but easily fixed by avoiding Apple's homegrown Java like the plague). www.java.com to get the official (Oracle) Java install for MacOS (or any other OS).
