TopLink/EclipseLink ExceptionHandler broken in SessionBroker because the code copy/paste initialization instead of delegating, and forget to handle ExceptionHandler in the copy/paste.

The bug exist since existance of SessionBroker so TopLink 9.x or before.

Workbench make it clear that ExceptionHandler is expected to be set at SessionBroker level, then will be attached to children sessions. In other words, Workbench allow only to set ExceptionHandler to the SessionBroker.

Code extract from SessionBroker.java:
 public SessionBroker acquireClientSessionBroker() {
        log(SessionLog.FINER, SessionLog.CONNECTION, "acquire_client_session_broker");
        SessionBroker clientBroker = copySessionBroker();
        clientBroker.parent = this;
        clientBroker.getIdentityMapAccessorInstance().setIdentityMapManager(getIdentityMapAccessorInstance().getIdentityMapManager());
        clientBroker.commitManager = getCommitManager();
        clientBroker.commandManager = getCommandManager();
        clientBroker.externalTransactionController = getExternalTransactionController();
        clientBroker.setServerPlatform(getServerPlatform());
...

and
  protected SessionBroker copySessionBroker() {
        SessionBroker broker = new SessionBroker(this.getSessionNamesByClass());

        broker.accessor = getAccessor();
        broker.name = getName();
        broker.sessionLog = getSessionLog();
        broker.project = project;
        broker.eventManager = getEventManager().clone(broker);
        broker.shouldPropagateChanges = shouldPropagateChanges;
	
        return broker;
    }
