I'll add this to Jira, but I was trying to narrow this down even more....
In my own test code, I split it into 2 separate bundles - 1 containing the
ServletContextHelper, the other containing the Servlet, both using
DS/Whiteboard
if I stop and start the servlet bundle only, I see this:
g! stop 22

It looks like the WebElement is never destroyed and removed when stopping
the Servlet Bundle - what makes this worse is that the WebElement *is still
accessible* via the original web path
if I just stop/start the Context bundle, this is where the original warning
is coming from, after which, the context is no longer available:
