Hudson fails to display any checkstyle details.

• It parses the checkstyle-result.xml files and displays correct numbers in the Warning Trend and
  Summary tables.
• The details tab is empty in the main page as well as the specific annotation type pages.
• Checkstyle plugin version 2.12 (though problem also noticed in previous versions)
• Hudson version 1.314
• Perhaps it is only partially parsing the <error/> lines. Ours look like
  <error line="58" column="32" severity="warning" message="'300' is a magic number."
  source="com.puppycrawl.tools.checkstyle.checks.coding.MagicNumberCheck"/>
• Result files generated using maven checkstyle plugin across many modules
