In trying to work around the issue detailed in this comment: https://ortussolutions.atlassian.net/browse/TESTBOX-43?focusedCommentId=14008&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14008, I added the CFC in question to the excludes argument list of my call to run():
However getBundle() was still being called for that CFC, and the new call was erroring.
CFCs in the excludes list should be completely excluded from the test run. Not read-and-discarded or whatever is going on now.
I have not thoroughly tested what's going on here, beyond trying to work around that other problem.
