The method ServiceController.register(ServiceContext ctx, Collection depends) throws Exception; can duplicate, triplicate or "n-plicate" ServiceProxy objects. This can happen when the deployment have many dependencys and register is called n-times.

a solution may be.:
/**

• Register the service context and its dependencies against the microkernel.
• If the context is already registered it does nothing.
  */
  private void register(ServiceContext ctx, Collection depends) throws Exception
  {
  boolean registered = installedServices.contains(ctx);

if ((registered) && (ctx.proxy != null))

{ //dont duplicate ServiceProxy objname return; }

else if (!registered) {
installedServices.add(ctx);

if (depends != null)
{
log.debug("adding depends in ServiceController.register: " + depends);
for (Iterator i = depends.iterator(); i.hasNext()

{ registerDependency(ctx.objectName, (ObjectName) i.next()); }

}
}

// Get the fancy service proxy (for the lifecycle API)
ctx.proxy = getServiceProxy(ctx.objectName, null);
}
