Re: [equinox-dev] Possible bug in ServiceTracker
|
Good eyesight. I guess I need to get my eyes checked. :-) That extra space
would do it.
The filter processor takes all characters from the operator to the close
parenthesis as the value. Such spaces may be part of the value being
matched and the filter processor does not know whether spaces can be
safely trimmed or not.
I suppose a filter processor implementation could special case objectClass
since it is a specified and well known attribute and it knows that class
names may not contain spaces...

Re: [equinox-dev] Possible bug in ServiceTracker
It looks like you have an extra space in you filter string before the last
')'
String filterString = "(" + Constants.OBJECTCLASS + "=" +
Content.class.getName() + " )";
We do not trim the trailing spaces on the string when doing string
matching. It may be nice to trim the trailing spaces but I'm not sure if
that is allowed by the spec.

Yeah, I kind of expected that.... Have a hard time understanding it could
have
passed this far otherwise.
My code (verbatimly tried) can be seen on;
http://rafb.net/paste/results/vUw1zc99.html
Not working --> http://rafb.net/paste/results/k2ONjs73.html
Working --> http://rafb.net/paste/results/4o6fYu32.html
If I comment out the Filter block, and replace with the String filter, it
works.
I will also try to test against some other OSGi container to see if it is
Equinox specific or not.
Cheers
