> We discovered this in 10.9.1.0 but I looked at the source in trunk and the issue is still there.
> To define a new sub-subprotocol (or I guess override an existing one?) by setting a system property, you are supposed to set "derby.subSubProtocol.myproto" with the name of your storage factory class as the value.
> Problem is, the way these are loaded strips the wrong prefix off the front of the string. BaseMonitor.java:
> {code}
>             if (key.startsWith(Property.MODULE_PREFIX)) {
>                 tag = key.substring(Property.MODULE_PREFIX.length());
>             } else if (key.startsWith(Property.SUB_SUB_PROTOCOL_PREFIX)) {
>                 tag = key.substring(Property.MODULE_PREFIX.length());
>             } else {
>                 continue nextModule;
>             }
> {code}
> So you get "rotocol.myproto" as the protocol you have to use in your connection strings.
