tracker issue : CF-3687315

Problem Description: 

I have noticed that after a reboot of our ColdFusion instances the scheduled tasks we had setup in the administrator weren't running correctly. 

When I looked in the http.log file I could see that it was trying to execute the correct template 

"Information","DefaultQuartzScheduler_Worker-9","10/25/13","07:18:16",,"Starting HTTP request {URL='...', method='get'}"

But the request never appears to be completed. When a task successfully runs I was expecting to see a completed line as well in the http.log file

"Information","DefaultQuartzScheduler_Worker-9","10/25/13","07:18:21", ,"HTTP request completed  {Status Code=200 ,Time taken=4896 ms}".

I have identified that this only occurs when the scheduled task is setup to use a proxy server.

 
Steps to Reproduce: 

-Create a scheduled task that requires a proxy server to access.
-Confirm the task is running successfully (check http.log).
-Restart the ColdFusion instance.
-Check the http.log file to see if the task is completing.

Actual Result:

It appears as though quartz attempts to trigger the task, but it never completes. The success message isn't added to the http.log and there are no entries in the apache access log for the URL of the scheduled task. 

Expected Result:

Task to have successfully completed and a HTTP request completed logged inserted into the http.log.

Any Workarounds:

-Go into the CF administrator and click on the task to edit.
-Save / Submit the form (no changes required)
-The task will then run as expected and complete successfully until the instance is restarted.
