java.lang.NullPointerException

  • 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.
