Bug in Flash Professional CC when launching debug launcher xml file handle not released

There appears to be a bug in either Adobe Flash Professional CC, or ADL when launching debug launcher for an AIR application Flash Professional CC automatically generates or updates the XML app descriptor file. The bug is that Flash Professional is not immedately releasing the file handle to the app descriptor XML file.

This bug was introduced in Flash Professional CC (Windows). It did not occur in CS5.5 or CS5.

The question is whether this is a bug related to the ADL, or if this bug is related specifically to Flash Professional CC (Windows).

Either way, where and how do I appropriately report this bug?
