Thanks Marcus, I have done the changes.

Hi Sharath,

Some minor nits:

In SyntheticAttributeExtension.java:
+                 eventTypeId = JdkTypeIDsPreJdk11.translate(eventTypeId);
                  if (REC_SETTING_EVENT_ID_ATTRIBUTE.getIdentifier().equals(fieldId)
                                  && JdkTypeIDs.RECORDING_SETTING.equals(eventTypeId)) {
                          return JfrInternalConstants.TYPE_IDENTIFIER_VALUE_INTERPRETATION;
                  }

The translated eventTypeId is only used once, instead of redefining the parameter, please consider just translating the eventTypeId where it is used: 
                  if (REC_SETTING_EVENT_ID_ATTRIBUTE.getIdentifier().equals(fieldId)
                                  && JdkTypeIDs.RECORDING_SETTING.equals(JdkTypeIDsPreJdk11.translate(eventTypeId))) {
                          return JfrInternalConstants.TYPE_IDENTIFIER_VALUE_INTERPRETATION;
                  }

[Sharath Ballal] Done.

Indentation problem in needTransform in JdkTypeIDsPreJdk11:

 211         /**
 212          * Determine if a typeId needs to be transformed into a JDK 11 type id.
 213          *
 214          * @param typeId
 215          *            type id
 216          * @return true if transformation is needed, false otherwise.
 217          */
 218         public static boolean needTransform(String typeId) {
 219                 if (typeId.startsWith(PREFIX)) {
 220             return false;
 221         }
 222                 return typeId.startsWith(EVENT_ID_ROOT) || typeId.startsWith(PREFIX_9_10) ;
 223         }
 224

[Sharath Ballal] Done

Kind regards,
Marcus

    The fix has undergone changes from last time as 'mvn verify' was failing.  The code changes now include: 
    
    1.      Changes to the V1 parser to use the SettingsTransformer for JDK 9 & 10 events.
    
    2.      Changes to some of the tests and their baseline files.
    
     
    
    Testing done:
    
    mvn verify passes.
    
    JDK 7/8/9/10 - Recording, loading and automated analysis works.  Verified that  scores of the automated analysis doesn't change from earlier.
    
    JDK 11 - Recording, loading and automated analysis works.
