Alternatively, the following would work and be simpler, if you prefer:


    public Object getAttribute(AccessibleAttribute attribute, Object... parameters) {
        getAttribute.attribute = attribute;
        getAttribute.parameters = parameters;
        return QuantumToolkit.runWithoutRenderLock(getAttribute);
    }
