Show the names of jobs which do not load properly.
As specified in JENKINS-4427 Jenkins should report which items fail to load. This may be annoying especially if you run a Jenkins instance with a lot of jobs after updating some plugins which are not backwards compatible.
If Jenkins loads the jobs in parallel it is not able to show the names of the offending jobs right now. A workaround is to disable parallel job loading by specifying
-Dhudson.model.Hudson.parallelLoad=false on the command line when starting Jenkins (See Hudson.java or the page about system properties for the specifics).
This will force Jenkins to use the code in line 2008 instead.
