      The following new api test fails on JDK1.5.0-b29:
      api/java_util/EnumMap/index.html#EntrySet[EntrySet006]
      api/java_util/EnumMap/index.html#KeySet[KeySet006]
      api/java_util/EnumMap/index.html#Methods[Methods001]
      api/java_util/EnumMap/index.html#Values[Values006]

      The API specification of the method EnumMap.clear reads:
        "Removes all mappings from this map."
        
      However RI does not remove mappings.

      The following simple test can be used to reproduce the failure:
      ===============================test.java=======================
      import java.util.EnumMap;

      public class test {
          public static void main(String[] argv) {
              EnumMap map = new EnumMap(simpleEnum.class);
              map.clear();
              System.out.println("Value: " + map.get(simpleEnum.FIRST));
              if(map.get(simpleEnum.FIRST) != null) {
                  System.out.println("Class: " + map.get(simpleEnum.FIRST).getClass());
              }
          }
      }
      ===========================simpleEnum.java=====================
      public enum simpleEnum { FIRST, LAST }
      ===============================================================
      $ javac -d . -source 1.5 test.java simpleEnum.java
