Eclipse log file including crash details.

Description of problem:

After upgrading to Fedora 31, opening eclipse fails and an error message is
shown, pointing to workspace/.metadata/.log , the contents of which are shown
(perhaps also including a successful launch after the crash?). The entries of
interest are those up until !ENTRY org.eclipse.osgi 4 0 2019-11-01
11:23:43.694, which includes the following error:
!ENTRY org.eclipse.osgi 4 0 2019-11-01 11:23:43.694
!MESSAGE Application error
!STACK 1

Quite a few of the of the previous log entries refer to requirements not being
found.

It was possible to workaround this issue by deleting ~/.eclipse, however, this
is obviously not ideal behaviour on upgrade.

For interest, it seems that a similar bug was noted in 2010:
https://bugzilla.redhat.com/show_bug.cgi?id=601352
(I have not marked this as a duplicate since given how much time has passed
this is probably a distinct issue).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to reproduce:
1. Use eclipse in Fedora 30

2. Upgrade to Fedora 31

3. Try to launch Eclipse

Actual results:

Crash

Expected results:
Eclipse opens successfully

I can not reproduce the issue. Do you still experience it?

This message is a reminder that Fedora 31 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 31 on 2020-11-24.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with
a
Fedora 'version' of '31'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 31 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

--- Comment #3 from Ben Cotton  ---
Fedora 31 changed to end-of-life (EOL) status on 2020-11-24. Fedora 31 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
