JavaVM FATAL: Failed to load the jvm library. JavaVM: Failed to load JVM: /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bundle/Libraries/libserver.dylib $ MyApp.app/Contents/MacOS/JavaApplicationStub I then tried opening the app from Terminal by running the Java application loader included in my app: This got rid of the alert, but despite being able to successfully run my jar from the command line, my app didn’t start.
