-*   Java
-    *   Logging Java: **InvalidSlf4jMessageFormat** (rulesets/java/logging-java.xml/InvalidSlf4jMessageFormat)<br/>
-        Check for invalid message format in slf4j loggers.
-*   java-comments/CommentRequired: New property `serialVersionUIDCommentRequired` which controls the comment requirements

-    with Override. See [PR#79](https://github.com/pmd/pmd/pull/79).
