Robert Scholte created MCHECKSTYLE-220:
------------------------------------------

URL: https://jira.codehaus.org/browse/MCHECKSTYLE-220
Project: Maven Checkstyle Plugin

As you can see, the search for the resource 'LICENSE.txt' continues. So there's no reason to show the stacktrace, it'll make thing very confusing.
