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
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.

JB,
to my understanding this isn't a known bug/issue of Karaf/Equinox/Felix
but an issue of the JVM, unless one uses a JDK8 he won't be able to
cleanup the perm space as all class definitions are stored there. As JDK8
doesn't have a perm space anymore (actually
JDK7 should already be better on
Correct, I talked about JVM depending of the classloader structures.

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

Hi Raman,

Each dev:restart execution uses around 80% of additional Perm Gen:
- 23,724,976 - 29,829,568 at first execution
- 29,829,568 - 35,809,616 at second execution

I gonna take a look in dev:restart command.

If using dev:restart with Karaf 2.2.9 with Equinox, the size of the permanent
generation increases drastically:
Permanent generation on initial start:
$ jmap -heap 27384
[...]
PS Perm Generation
used = 50648144 (48.30183410644531MB)
After dev:restart, perm gen size is about 75% bigger:
Hi Raman,
Users mentioned that with Equinox as well.
I didn't try with Felix (I will). Not sure we can do something in Karaf,
I will take a look.
