excludedGroups property does not work with JUnit

If i use the groups property in my maven configuration everything works how expected. The plugin only selects the tests with the specific category. On the other Hand, if i use the excludedGroups property the plugin could not find any tests to run.

<excludedGroups>de.test.junit.categories.IntegrationTest</excludedGroups>
</configuration>
