Clicking on Clover tab results in "Internal server error" in Bamboo

[Marek Parfianowicz]

In Bamboo 5.4 or 5.4.1 when I click on the "Clover" tab in order to see a plan summary, a Bamboo server displays an error page with a stack trace like this:

How to fix it?

This is a bug: https://jira.atlassian.com/browse/BAM-14334, which has been fixed in Bamboo 5.4.2. You have to upgrade your Bamboo server.
