Michael Bielkiewicz Posted September 5, 2023 Share Posted September 5, 2023 It seems to me that something is wrong with your compiled JAR. I do not sign any custom JARs that I create - I would try to recompile it with various options - should be pretty plain/vanilla. Also, ensure you are compiling to the same version of Java that you have deployed on your server (i.e. if you are running JRS with Java 8, make sure your IDE is using Java 8 to build the JAR file. I hope this helps. Link to comment Share on other sites More sharing options...
