      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)

      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. MetaClass should probably annotate linkage errors with the starting class, for diagnosis.
