[jbosstools-issues] [JBoss JIRA] (JBDS-4175) RPM version: NPE after install from Red Hat Central

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.

>          Components: rpm
>         Environment: RHEL 7.2 with RHSCL repositories available:

>  * update for RHBZ#1392095 (http://nest.test.redhat.com/mnt/qa/scratch/vkadlcik/eclipse/repos/rhscl23z/v02/)

> 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.
