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.
A quick fix is available in the source scanner. The quick fix replaces uses of the LinkedHashMap.Entry class with the Map.Entry class.
