This rule flags the java.util.LinkedHashMap.Entry class. The IBM Java 6 SDK used a customized version of the Apache Harmony libraries to implement the java.util.* package, which allowed access to the LinkedHashMap.Entry class. However, the IBM Java 7 SDK uses the Oracle implementation of the java.util.* package, which does not expose the LinkedHashMap.Entry class. If your application references the LinkedHashMap.Entry class, you should instead use Map.Entry.
An automated fix will replace the use of LinkedHashMap.Entry class with the Map.Entry class.
