This is going to sound like a strange fix but I've had it work on 2 systems:
download: libequinox-osgi-java_3.8.1-10_all.deb https://packages.ubuntu.com/artful/all/libequinox-osgi-java/download Install it with dpkg or similar) Run netbeans. It should load. Run sudo apt upgrade to get the bionic version back. Run netbeans. For me it still works. In other words something about running with 3.8.1-10 fixes whatever the issue is. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776937 Title: netbeans crash during loading: java.lang.NullPointerException at org.eclipse.osgi.baseadaptor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netbeans/+bug/1776937/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
