Grouper Users - Open Discussion List

I am using Grouper 2.4 with all recent patches installed. I get an error when I try to call the GetSubjects method using the Web Service.

java.lang.NoSuchMethodError: edu.internet2.middleware.grouper.subj.SubjectHelper.convertToMultiKey(Ledu/internet2/middleware/subject/Subject;)Lorg/apache/commons/collections/keyvalue/MultiKey;

I see this source file contains getSubjects() which calls convertToMultiKey(subject)
grouper-ws/grouper-ws/src/grouper-ws/edu/internet2/middleware/grouper/ws/GrouperServiceLogic.java

I see that convertToMultiKey() is here in the Tomcat directory
$ grep convertToMultiKey /var/tomcat/grouperdev/webapps/grouper-ws/WEB-INF/classes/edu/internet2/middleware/grouper/subj/SubjectHelper.java
  public static MultiKey convertToMultiKey(Subject subject) {

so it is strange that the method is not found by the Web Service. Any advice would be appreciated.
