Description

I'm running Felix embedded inside a webapp, running in Tomcat.

Tomcat installs its own URLStreamHandlerFactory. Felix swaps it out correctly when I start it, and seems to delegate properly. When the webapp is unloaded, however, and it stops Felix, it does not restore the previous implementation, but rather leaves the existing URLHandlers instance installed. Then, if I try to redeploy the webapp without restarting the JVM, I get errors, because Tomcat automatically sets the URLHandlers class's static members to null when it unloads the webapp. (see https://issues.apache.org/bugzilla/show_bug.cgi?id=41939)

I've tested this on 1.2.1 and 1.4.0, and both versions have this problem.
