WO bug fixes

Just out of interest, do people see WO bugs they report to Apple being 
fixed? I expect some people are treated with higher priority? Over the last 
few years I have filed perhaps 10 bugs. Some of my earlier reports just 
vanished. I can now see 5 on radarweb, all Open. I have been contacted once 
or twice with further questions, but have never seen one of my bug reports 
marked as resolved!

My top bug is that asking for requests to be handled concurrently for a 
Java Client application server side is apparently ignored. I am sure this 
was working a few releases ago. I suppose I shouldn't hold my breath.
