Ive put in in  jboss\server\default\lib in a jar. And my a small modification to respect inheritence.

public class BMTTxInterceptorFactoryCustom extends BMTTxInterceptorFactory {

    @SuppressWarnings("unused")
    private static final Logger log = Logger.getLogger(BMTTxInterceptorFactoryCustom.class);

    public Object createPerJoinpoint(Advisor advisor, Joinpoint jp) {
        // We have to do this until AOP supports matching based on annotation attributes
        TransactionManagementType type = TxUtil.getTransactionManagementType(advisor);
        if (type != TransactionManagementType.BEAN)
            return new NullInterceptor();
        TransactionManager tm = TxUtil.getTransactionManager();
        boolean stateful = advisor.resolveAnnotation(Stateful.class) != null;
        // Both MessageDriven and Stateless are stateless
        if (stateful)
            return new StatefulBMTInterceptor(tm);
        else
            return new StatelessBMTInterceptor(tm) {
                @SuppressWarnings("unused")
                protected void handleException(Invocation invocation, Exception ex) throws Exception {
                    if (ex == null) {
                        return;
                    }
                    ApplicationException ae = (ApplicationException) invocation.getAdvisor()
                            .resolveAnnotation(ApplicationException.class);
                    // it's an application exception, so just throw it back as-is
                    if (ae != null || ex.getClass().isAnnotationPresent(ApplicationException.class)
                            || isApplicationExceptionPresentInParent(ex.getClass().getSuperclass())) {
                        throw ex;
                    }
                    if (ex instanceof EJBException) {
                        throw (EJBException) ex;
                    } else {
                        throw new EJBException(ex);
                    }
                }
            };
    }

    private boolean isApplicationExceptionPresentInParent(Class<?> parent) {
        if (Object.class.equals(parent))
            return false;

        ApplicationException anot = parent.getAnnotation(ApplicationException.class);

        if (anot != null)
            return anot.inherited();
        else
            return isApplicationExceptionPresentInParent(parent.getSuperclass());

    }

}
