I've been trying to upgrade from 1.434 using the automatic upgrade for some time now. First to version 1.436, then 1.440 and today to 1.441 but all with no luck. I've also updated all plugins before the Jenkins upgrade. After the upgrade I get a stacktrace and then I just revert back to 1.434. Here is the stacktrace:

Any workaround also appreciated.
