Page loads breaks when View.getItems fails

Reporter: Jesse Glick

It is not uncommon for an error to be thrown from View.getItems. Currently Jenkins behaves poorly in this case: it displays an "oops" page with a cryptic stack trace

java.lang.NullPointerException: Cannot invoke method isEmpty() on null object
at org.codehaus.groovy.runtime.NullObject.invokeMethod(NullObject.java:77)
at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:45)
at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:42)
at org.codehaus.groovy.runtime.callsite.NullCallSite.call(NullCallSite.java:32)
at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:42)
at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:108)
at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:112)
at hudson.model.View.main.run(main.groovy:6)

that has no relation to the real error.

Re: Page loads breaks when View.getItems fails

Linking to some examples of this, but from this search you can see there at least a dozen cases.
