We're running macOS Mojave, fully updated, with amazon Corretto 8 JDK. When users launch Oracle's SQLDevelper app while plugged into their Targus DisplayLink docks, the app crashes 100% of the time. The SQLDeveloper app is built on Java so this definitely counts as a problem. I tried using the DisplayLinkJavaTest.jar, but I get the following error when I try to run the test:
Code:
java -jar DisplayLinkJavaTest.jar Error: A JNI error has occurred, please check your installation and try again Exception in thread "main" java.lang.UnsupportedClassVersionError: Main has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:763) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:468) at java.net.URLClassLoader.access$100(URLClassLoader.java:74) at java.net.URLClassLoader$1.run(URLClassLoader.java:369) at java.net.URLClassLoader$1.run(URLClassLoader.java:363) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:362) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:495) |

I have tried the build 19 and the newest build 26, both of them pass on all the tests given by DisplayLinkJavaTest.jar but neither of them fixes my issue. After changing to build 19, java-based softwares started but then went into an everlasting "Application Not Responding", and upon a reboot of the computer these softwares don't start at all, they just crash upon opening them, just like before. This same thing happened with build 26. This has only been tested on MacOS 10.14.6 though, as this is the system I am using. Regards, Timothy |

Does it pass all tests from DisplayLinkJavaTest.jar ? I expect they don't as this is a build without a fix. This is important thing to understand the problem. If we will know that we can push java guys to port the fix to older jdk. Please keep in mind that this is early development(unstable) build of jdk and other java issues you are experiencing are expected. |

This is important as we need to know if the fix that Oracle supplied is sufficient. If so we can push them to port it to older jdk version. |

We cannot. We are strictly locked in to JDK 8. Not even for testing purposes.

I should clarify that we are running macOS Mojave 10.14.6 and DisplayLink 5.2.1 and this problem still exists. We need a solution to this.

I am also having this problem. It's been driving me absolutely CRAZY; my Java apps have been crashing and I had no idea that the DisplayLink drivers were causing the issue.
I removed the DL hardware from my system and wha-la! All of my apps are now working perfectly. @DisplayLink--please fix this issue ASAP. I am not able to use my expensive Targus dock now, which is not making me very happy about the investment. |
