     [ https://issues.jboss.org/browse/JBIDE-18031?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mickael Istria updated JBIDE-18031:
-----------------------------------

    Description: 
1. Install JBT 4.2.0.Beta3 or CR1 (nightly) into Eclipse Luna eclipse-jee-luna-R-linux.gtk.x86_64.tar.gz
2. Launch JBT, and Central will open by itself (default)
3. Select Software/Update tab
4. Close Central
(So far, so good.)

5. Reopen it from the coolbar icon.
7. Select "Show Early Access" checkbox (enable or disable, whichever shows that same issue)

Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".

Restarting Eclipse/JBDS "resets" the error so first Central page works fine, but the bug is still there for next times you'll open Central. 

  was:
1. Install JBT 4.2.0.Beta3 or CR1 (nightly) into Eclipse Luna eclipse-jee-luna-R-linux.gtk.x86_64.tar.gz
2. Launch JBT, and Central will open by itself (default)
3. Select Software/Update tab
4. Enable the "Enable Early Access" box, and click "Yes" to accept.
5. Disable the "Enable Early Access" box, and click "OK" to acknowledge.

(So far, so good.)

6. Close Central, then reopen it from the coolbar icon.
7. Repeat steps 4 and 5. This time, you will see errors such as this:

8. Restart Eclipse. Errors go away. (Steps 4-5 work as expected.)

9. Close and re-open Central. Errors are back. (Steps 4-5 throw errors.)
