AFAIR, the PermSize increase is a known issue: dev:restart creates a new
classloader for each bundle, but the previous classloader is not
unloaded by the JVM.

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.

JB, did you have a chance to take a look at this?
Do you want me to create an entry in Jira?
