OIM 11gR2 - RoleUser PostProcess Event Handler not triggered

Question

Hi,
I'm trying to create a postprocess event-handler for RoleUser entity so that when a role is assigned (or removed) to a user an UDF is populated with the list of its roles.
I developed my event-handler and registered it following instructions on http://docs.oracle.com/cd/E27559_01/dev.1112/e27150/oper.htm#OMDEV4749 but the event-handler is not triggered.
I've read and tried a lot of things but nothing seems to work.
I use System.out.println() and a Logger in the event-handler methods as well as breakpoints debugging via Eclipse, all this indicates the event-handler is not triggered.
I checked the event-handler is registered by using getEventHandlers(RoleUser,CREATE) method on IAMAppDesignMBean through Enterprise Manager. Result is :
Postprocess,-2147483648,PostProcessingInitiation,/metadata/iam-features-request/event-definition/EventHandlers.xml,true
Postprocess,FIRST,MyHandler,Plugin:MyHandler,false
Postprocess,FIRST,MyHandler,Plugin:MyHandler,false
Postprocess,FIRST,MyHandler,Plugin:MyHandler,false
Postprocess,FIRST,MyHandler,Plugin:MyHandler,false
Postprocess,1020,RoleGrantPostProcessActionHandler,/metadata/iam-features-identity/event-definition/EventHandlers.xml,false
Postprocess,9988,AsyncHandler,/metadata/iam-features-asyncwsclient/EventHandlers.xml,true
Postprocess,3000000,CallBackOAACGWithApprove,/metadata/iam-features-rolesod/EventHandlers.xml,true
Postprocess,2147483647,RequestCompleted,/metadata/iam-features-request/event-definition/EventHandlers.xml,true
Note that I dont understand why the handler appears four times..
Also, when I unregister it, it still appears one time.
Here is my event handler XML file (in META-INF folder of the plugin zip) :
<?xml version='1.0' encoding='utf-8'?>
<eventhandlers
  xmlns="http://www.oracle.com/schema/oim/platform/kernel/"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.oracle.com/schema/oim/platform/kernel orchestration-handlers.xsd">
  <action-handler
  class="package.MyHandler"
  entity-type="RoleUser"
  operation="ANY"
  name="MyHandler"
  stage="postprocess"
  order="FIRST"
  sync="TRUE" />
</eventhandlers>
plugin.xml file (root of plugin zip) :
<?xml version="1.0" encoding="UTF-8"?>
<oimplugins xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <plugins pluginpoint="oracle.iam.platform.kernel.spi.EventHandler">
  <plugin
  pluginclass="package.MyHandler"
  version="1.0"
  name="Myhandler" />
  </plugins>
</oimplugins>
Java code (in a JAR in lib folder of plugin zip) :
public class MyHandler implements PostProcessHandler {
@Override
public EventResult execute(long processId, long eventId, Orchestration orchestration) {
  System.out.println("Inside EventResult execute ");
  LOGGER.log(Level.SEVERE, "Inside eventResult execute");
  // Some code
  return new EventResult();
@Override
public BulkEventResult execute(long processId, long eventId, BulkOrchestration orchestration) {
  String operation = orchestration.getOperation().trim().toString();
  System.out.println("<---------- Calling " + getClass().getName() + ": Operation[" + operation + "] Execute ---------->");
  LOGGER.log(Level.SEVERE, "Inside BulkEventResult execute");
  // Some code
  return new BulkEventResult();
Maybe I'm missing something ? Any help would be really appreciated
Thanks,
Gael
EDIT :
Also note that I see these messages in the logs but I'm not sure it concern my event handler from what I read on some pages :
XML schema validation failed for XML eventhandlers and it will not be loaded by kernel.
[CALLBACKMSG] Found 0 possible matches for applicable policies for step POST_PROCESS, entity RoleUser, operation CREATE.

I eventually got it working but I'm not sure of how.. !
I changed the name of the handler (it was not "MyHandler" but something very long, I shortened it). I copy and paste exactly what was described here : Post process event handler when a role is created or modified in OIM. I did purge cache. I tried to apply it on another entity (Role), it was triggered, then I applied it back to RoleUser and it still works.
If it can help someone, my plugin zip contains :
plugin.xml :
<?xml version="1.0" encoding="UTF-8"?>
<oimplugins xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <plugins pluginpoint="oracle.iam.platform.kernel.spi.EventHandler">
  <plugin pluginclass="fr.xxx.RoleUserProcessor"
  version="1.0" name="RoleUserProcessor" />
  </plugins>
</oimplugins>
META-INF/EventHandlers.xml :
<?xml version="1.0" encoding="UTF-8"?>
<eventhandlers xmlns="http://www.oracle.com/schema/oim/platform/kernel"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.oracle.com/schema/oim/platform/kernel orchestration-handlers.xsd">
  <action-handler class="fr.xxx.RoleUserProcessor"
  entity-type="RoleUser" operation="ANY" name="RoleUserProcessor" order="9999"
  stage="postprocess" sync="TRUE" />
</eventhandlers>
lib/xxx.jar/RoleUserProcessor.java :
@Override
  public EventResult execute(long processId, long eventId, Orchestration orchestration) {
  LOGGER.log(Level.INFO, "Execution RoleUserProcessor EventHandler (mode non bulk)");
  String operation = orchestration.getOperation().trim().toString();
  LOGGER.log(Level.INFO, "Operation : " + operation);
  return new EventResult();
  @Override
  public BulkEventResult execute(long processId, long eventId, BulkOrchestration orchestration) {
  LOGGER.log(Level.INFO, "Execution RoleUserProcessor EventHandler (mode bulk)");
  String operation = orchestration.getOperation().trim().toString();
  LOGGER.log(Level.INFO, "Operation : " + operation);
  return new BulkEventResult();
Thank you
Also, a thing that may help some people, I found out that the ORCHEVENTS table in OIM schema contains the history of handlers triggered.
