Subject cvs commit: jakarta-commons/modeler/src/java/org/apache/commons/modeler BaseNotification.java

  Modified:    modeler/src/java/org/apache/commons/modeler
                        BaseNotification.java
  Log:
  Some work on the base notification.
  
  The goal is to make it recyclable and support "notes" ( i.e. int-based array accessors
  to attributes - like "handles" or descriptors), that would make the jmx notification
  a good replacement for the current callbacks in coyote and jk ( and anything else ).
  
  This is not yet complete - we also need an mbean to act as an "Id manager" and
  maintain the int ids.
