This issue affects Ubuntu 18.04 LTS (Bionic Beaver)
Reproduction:
1. Install netbeans
2. Try starting netbeans
It crashes during the loading screen. In `~/.netbeans/8.1/var/logs/messages.log` I see the following:

Possibly related to this debian bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891957
I also tried stealing the netbeans 8.2 packages from debian experimental, which use openjdk-11 instead of openjdk-8, but they ran into the same issue.
The debian bug suggests it might be related to the package `libequinox-osgi-java`, but since the netbeans package is the one that I actively observe crashing, I'm filing it against this one instead.
It's worth pointing that, under some circumstances (that I don't fully understand), I can also get this error instead:

Either way, I haven't managed to get the default, packaged `netbeans` to work at all. Does this work for anybody else?
