Report, not discard, caught exception in ctor

The PortalRestCentralServiceImpl constructor instantiates a class by
name then calls methods on the new object.  The ctor uses try/catch
but if an exception occurs, the ctor discards that exception and
throws ClassCastException with a vague message.  Change to throw
ServletException and include the cause exception.
