There were errors loading this plugin. Please see the logs for more information.

Also, each component of the plugin has "Error:" written underneath it, but only the component that had the error prints a message - everything else is blank. e.g.

Participants of an issue (participants)
Displays reporter, current assignee and all commenters of the issue
Error:
Multiple Project Searcher (multiprojectsearcher)
Search for true only
Error:
Dummy Project Field (multiproject)
Error: There was a problem loading the descriptor for module 'Dummy Project Field' in plugin 'JIRA Toolkit Plugin'. java.lang.VerifyError: class com.atlassian.jira.toolkit.customfield.DummyProjectCFType overrides final method.

Could we hide the "Error:" label if there is no message to print?
