Should I upgrade to Java 18? And if so, what's the best way to do it? Can anyone help me out? I'v been on other forums, but I'm not sure what I need to sak, and I think I may have gotten under some people's skin. But even thought I've dabbled before in Linux - and I just mean dabble, since I always had my OS X - I'm not sure what's going on. I was able to compile the file, and then I got this error when I entered 'java MainWindow':Įxception in thread 'main' : Can't load library: /usr/lib/jvm/java-17-openjdk-amd64/lib/libawt_xawt.soĪt java.base/(ClassLoader.java:2393)Īt java.base/0(Runtime.java:755)Īt java.base/(System.java:1953)Īt java.base/.load(Native Method)Īt java.base/$NativeLibraryImpl.open(NativeLibraries.java:388)Īt java.base/.loadLibrary(NativeLibraries.java:232)Īt java.base/.loadLibrary(NativeLibraries.java:174)Īt java.base/.findFromPaths(NativeLibraries.java:315)Īt java.base/.loadLibrary(NativeLibraries.java:285)Īt java.base/(ClassLoader.java:2398)Īt java.base/0(Runtime.java:818)Īt java.base/(System.java:1989)Īt sktop/$2.run(Toolkit.java:1392)Īt sktop/$2.run(Toolkit.java:1390)Īt java.base/(AccessController.java:318)Īt sktop/(Toolkit.java:1389)Īt sktop/(Toolkit.java:1427)Īt sktop/.(Toolkit.java:1401)Īt sktop/.(Component.java:624)Įverything works fine on my MB Pro. : MainWindow has been compiled by a more recent version of the Java Runtime (class file version 62.0), this version of the Java Runtime only recognizes class file versions up to 61.0 Before when I tried to run the file w/o compiling I got this error:Įrror: LinkageError occurred while loading main class MainWindow There's a file that I want to run which contains the main method to get things going - 'MainWIndow.java' I can compile the file. I have a folder labeled 'Contacts Java Classes', and I know how to get to the folder, etc. I'm working on a project as a way of learning Java. I 'm running elementary OS, and was able to download and install the Open JDK for Java 17. I have experience with the command line in the Terminal app, so most of the commands - at least the basic ones - I'm familiar with in Linux. I've dabbled with Linux in the past, but my MB pro is dying - started yesterday, in fact - and it's time to switch.

Java version update
