[JIRA] (JENKINS-15892) Jenkins fails to start after error in hudson.maven.PluginImpl.init

Wed, 21 Nov 2012 11:04:45 -0800

Issue Type: Bug Bug
Assignee: Unassigned
Components: core
Created: 21/Nov/12 7:04 PM
Description:

Start 1.490 on a clean home dir, then ask to upgrade the Maven plugin to version 1.491, and restart. After the restart, there are linkage errors from the Maven plugin, predictably enough (since it is using 1.491+ core APIs); but all of Jenkins fails to start, making it impossible to use the GUI to back out the update. (Workaround: delete $JENKINS_HOME/plugins/maven-plugin.jpi.pinned.)

followed by various errors from hudson.ExtensionFinder$Sezpoz.scout and similar; and then

Exception in thread "pool-2-thread-3" java.lang.NullPointerException

	at java.lang.Thread.run(Thread.java:722)

followed by Jenkins shutting down (and throwing some more errors).

If a plugin fails to start due to linkage errors, it should be disabled, but that should prevent the whole application from starting.
