Just upgraded to cobertura 1.9. Forgot a jar for a build or so. Got lots of errors like [cobertura-instrument] WARN addInstrumentationToSingleClass, Unable to instrument file [.../Foo.class] 06-Jun-2007 10:15:13 [cobertura-instrument] java.lang.NoClassDefFoundError: org/​objectweb/​asm/​tree/​MethodNode Added new jar. cobertura is happy again. But the plugin is not. Clicking the coverage tab on any build plan page gets me the stack trace below. Haven't tried upgrading Bamboo or reindexing yet. No reason to think either will help.
