Hi Richard,
There is actually a JIRA issue for latter issue (don't know the number...i am traveling).
Its FELIX-38 and contains a link to the respective Eclipse bug.
Do you have a need for it now or are you just wish listing?
Unfortunately I have a need for this, as my application will run inside a servlet container and must support running in an application server and requires custom URL stream handlers .... If you don't mind, I will take care of this and try to prepare a patch along the lines of Eclipse. Regards Felix
