Description

When ByteArrayResource#getData(org.apache.wicket.request.resource.IResource.Attributes) returns null, the class throws a WicketRuntimeException.

This behavior differs from DynamicImageResource and ResourceStreamResource which instead issue the following call:
response.setError(HttpServletResponse.SC_NOT_FOUND);

ByteArrayResource should follow the same behavior. This would allow for instance to use it for resources which depend on the contents of attributes.getParameters(). When the parameters are invalid, a 404 should be issued instead of an exception.
