Hmm,

if I'm not completely wrong a dev:restart keeps the JVM up and running.
So this isn't an issue of Karaf/Equinox/Felix or whatsoever it's an issue
of
the JVM itself that isn't capable of cleaning the Perm Space.
As the command already states this is a development command and is not
supposed to be used in Production!
You'll see the same behaviour with any container supporting hot
replacement.
