Netbeans 8.1 crash in splash screen

[Phelps Scofield]

The splash screen displayed normally but disappeared during the step that turned on the modules.

Is this the same as LP: #1763091 ? If so, I will dupe it (as I'm hoping to resolve that today).

No, I'm already using java 8 and I uninstalled open-jdk9 and 8, but netbeans is just the splash screen

My netbeans crash in Turning on modules, in the splash screen.

[Alexander (neoexpert)]

It crashes even after fresh installation of Ubuntu 18.04 and afterwards netbeans installation with

sudo apt install netbeans.

Some other Java programs (at least eclipse) do not start too.

netbeans 8.2 does start, but after opening a maven project there are no files displayed in the navigator-view

same issue fetching after upgrade new ubuntu version. netbeans crash in Turning on modules, in the splash screen.

There have any solution?

I've been looking into this bug myself (Launchpad's duplicate finder isn't suggesting this bug as a duplicate target so it's been reported several times by many people, including me). My findings are summarised in #1776724.

Unfortunately I don't know what's causing it, but there might be enough information there to go on.

[ais523 (ais523)]

Although the original bug report was incomplete, there's more complete information at the duplicates.

Marking as confirmed because the bug affects multiple users.

[ais523 (ais523)]

Upstream bug report: https://issues.apache.org/jira/browse/NETBEANS-756?jql=project%20%3D%20NETBEANS%20AND%20text%20~%20crash

(I can't link this to the Launchpad report the usual way because Netbeans has changed bug tracker, and Launchpad will only acknowledge the old tracker's URL.)

Netbeans apparently consider this to not be a bug (!), on the basis that it expects some of its folders which are currently stored under /usr/share to be user-writable. Presumably, this is a packaging issue; if the software is going to assume that directories are user-writable we're going to have to move them to dotfiles or the like. It would help to get clarification on exactly which parts of the directory are meant to be writable; "all of it" would a) be horrible practice and b) make packaging it very difficult, because a large amount of fixed content is meant to be stored there.

Re comment 2, I believe there are two bugs here, but this is the important one. People are seeing a crash accompanied by a warning about a Java 9 deprecation, and assuming they're connected, and thus are reporting the Java 9 deprecation (#1763091). However, the crash occurs even without the use of Java 9 (this bug), and in an identical way regardless of which version of Java is used.

It's not clear what the most useful way to track this in the bug tracker would be. Marking them as duplicates would probably not be technically correct, but might be most useful for end users (who are likely to see the two bugs at the same time). At the very least, there should be clear pointers back and forth.

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.

[elatllat (elatllat)]

Those packages only have 3/(48 and 21) files in common.

vimdiff <(dpkg-deb -c libequinox-osgi-java_3.8.1-10_all.deb | perl -pe 's/.* //g;s/^\.\//\//g' | sort) <(dpkg-query -L libequinox-osgi-java | sort)

Ubuntu and derivatives from version 18.04 is only compatible with version 8.2 of Netbeans, so I solved this problem.
