Issue Type: Bug Bug

Components: core

Description:

In 1.480 I encountered an unreproducible exception:

java.lang.NoClassDefFoundError: org/apache/maven/plugin/MojoExecution
	at java.lang.Class.getDeclaredMethods0(Native Method)
	at java.lang.Class.privateGetDeclaredMethods(Class.java:2442)
	at java.lang.Class.privateGetPublicMethods(Class.java:2562)
	at java.lang.Class.getMethods(Class.java:1427)

	at jenkins.model.GlobalPluginConfiguration.config.run(config.groovy:8)


Something wrong the Maven plugin, presumably. Yet the error recovery was poor: the /configure screen displayed the exception but failed to complete loading.



    
	
  1. Functions.hasView should catch various errors and just return {[false}}.
    2. 
	
  2. MetaClass should probably annotate linkage errors with the starting class, for diagnosis.
    3.
