Please clarify when you do get the error. Does the error show up when trying to install content, or restart after install, or when trying to use the plugins?

It would be interesting to try an installation with regular p2, using directly some p2 site for, let's say, Spring IDE and install them with the regular p2 wizard, or even with the p2 headless director. I don't think Central itself is to blame here.

NPE/broken functionality/cannot start after install from Red Hat Central into rh-eclipse46-devstudio ---------------------------------------------------------------------------------------------------- Key: JBDS-4175 URL: https://issues.jboss.org/browse/JBDS-4175 Project: Red Hat JBoss Developer Studio (devstudio) Issue Type: Bug Components: central-update, 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 Assignee: Nick Boldt Priority: Critical Fix For: 10.2.0.GA Attachments: JBDS-4175_logs_first_half.tar.gz, rh-eclipse46-devstudio10.2.log.20161115-0953.txt, spring-ide-fail-aop.png, spring-ide-fail-list.png, spring-ide-fail-npe.png, spring-ide-fail-project-explorer-broken-package-explorer-OK.png, spring-ide-fail.png, spring-ide-view-fail.png, sw_to_install.txt, workspace.log, wst.xsd.core_diff.png 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.
