4.3 Beta 3: Java Apps crash on launch if connected to external DisplayLink device
Hi there,
4.3 beta 3 looks good so far, except I noticed some Java apps I normally use failed to launch. I even figured it was Java itself and re-installed it many times with the same issues. As it turns out, when the DisplayLink device is not connected, the Java apps will launch correctly. How to reproduce: 1. Connect first monitor as normal 2. Connect second monitor via Diamond BVU 195 3. Ensure DisplayLink 4.3 beta 3 software driver is installed 4. Properly set up as "Using separate display" in AirPlay 5. Go to "System Preferences" app 6. Open "Java" preference pane * Notice Java Control Panel should open, but doesn't 7. Click "Reopen the Java Control Panel" button * Again notice Java Control Panel does not open 8. Try with other AWT-based Java apps (one example below with crash log) 9. Disconnect DisplayLink device 10. Click "Reopen the Java Control Panel" button * Notice now this opens without issues Example output from command line attempt to run yEd graph editor from: https://www.yworks.com/products/yed/download Code:
