Bug Description

I upgraded from 16.04 to 18.04 on Friday. Following some reboots and updates this morning I am now unable to start the Eclipse IDE. This was working before the upgrade.

I have the C++ developer support added to Eclipse. To the best of my memory (and ability to interrogate apt) it is all installed from the Ubuntu repositories.

When I click the Eclipse launcher pinned to my side bat I get an error message from Eclipse that reads:
An error has occurred. See the log file
/home/thomas/.eclipse/org.eclipse.platform_3.8_155965261/configuration/1532947738216.log

Viewing the log file I see:

This is easily repeatable.

Some internet searching suggests this problem is present upstream as there is a Debian bug that looks similar: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891956

Reviewing the Debian equivalent people have suggested that:

$ sudo apt-get install --reinstall libequinox-osgi-java

Could resolve the issue. Although some people note that it does not help. Others have recommended completely removing Eclipse as installed through apt and instead using the version supplied directly on the Eclipse CDT webpage https://www.eclipse.org/cdt/

I shall try both solutions this afternoon if there are no alternatives suggested that people would like me to try.

I can confirm that downloading the Eclipse installer from the main website: http://www.eclipse.org/downloads/ executing it as myself and then selecting the C/C++ option got me a working copy of Eclipse installed. That is a successful work around until the packaged version is fixed.

When I ran the install I did see some errors that I will bring up with the Eclipse team, if I can work out how:

However despite the above it did seem to install fine.

I have raised https://bugs.eclipse.org/bugs/show_bug.cgi?id=537526 to cover the installer issue. There are similar bugs marked as fixed for the main Eclipse code, but as this is still visible and relates to the installer, not the main binary, I raised a new bug.

That is probably all from me for now. I shall await news of an updated package to test out or some instructions of other things to try.
