While working with LDAP configuration, I've noticed that if I make any change to say a deployed, login module, I receive "service unavailable errors" on my next execution:

I've tried, removing everything from the hot deploy directory and re-deploying, refreshing bundles, same error, e.g:
karaf@root> list |grep -i ldap
[ 202] [Active ] [Created ] [ ] [ 60] my_ldap_karaf_module_apacheds.xml (0.0.0)
[ 203] [Active ] [Created ] [ ] [ 60] my_ldap_amq_module_openldap.xml (0.0.0)
[ 204] [Active ] [ ] [ ] [ 60] my_LdapSrpingBroker-broker-openldap.xml (0.0.0)
--> Un-deploy stuff and verify it's gone:
karaf@root> list |grep -i ldap
karaf@root>
Only restarting servicemix seems to clear it.
Test Case Set-up
1. Set up the environment as detailed in
ESB-1445 for the Spring use case. Ignore the blueprint stuff.
2. Run the ProducerTool Demo from activemq:
3. Edit the ./deploy/my_ldap_amq_module.xml and add a space in a comment card or something trivial, save.
4. Re-run the Producer Tool Demo
I spotted this Karaf bug,
https://issues.apache.org/jira/browse/KARAF-344
, which may be related. It was recently closed as unable to reproduce. The scenario is a bit different but maybe it will help.
Bug

Major
When changing an hot deployed ldap login module, I have to restart servicemix to pick up the changes
