Nick Boldt commented on JBDS-4175:
----------------------------------
If the error is "Another singleton bundle selected" it just means that two
versions of the same bundle exist in the installation, and only one singleton can be
activated.
Chances are good this is just a warning, not an error, and can be simply ignored.
RPM version: NPE after install from Red Hat Central
---------------------------------------------------
Key: JBDS-4175
URL:
https://issues.jboss.org/browse/JBDS-4175
Project: Red Hat JBoss Developer Studio (devstudio)
Issue Type: Bug
Components: rpm
Environment: RHEL 7.2 with RHSCL repositories available:
* RHSCL 2.3 RC
(
http://download-node-02.eng.bos.redhat.com/rel-eng/RHSCL-2.3-RHEL-7-RC-1....)
* update for RHBZ#1392095
(
http://nest.test.redhat.com/mnt/qa/scratch/vkadlcik/eclipse/repos/rhscl23...)
Reporter: Václav Kadlčík

I installed rh-eclipse46-devstudio-10.2-0.20161111.0219.el7.x86_64.rpm and followed
Nick's scenario [1]. In Red Hat Central, I clicked "Select All" (it found 36
items), then "Install/Update", did all the confirmations, including a restart.
After the restart, Eclipse died on java.lang.NullPointerException. I'm attaching the
workspace log (aside from the NPE, it's full of "Could not resolve
module").
I reproduced the problem several times on two different machines. The update for
RHBZ#1392095 (rh-eclipse46-eclipse-4.6.1-2.4.el7) isn't necessary, it just makes the
reproduction much faster.
Not sure how related it is, but rh-eclipse46 disallows updating packages installed from
RPM [2]. But in the list of software to be installed/updated, I saw, among others, EGit
and Mylyn, which are definitely included in rh-eclipse46-base. In any case, I'm
attaching the list, too.
