This is likely related to:
https://issues.apache.org/jira/browse/FELIX-2913
Which was ultimately impacted by the following changes for framework 3.2.0:
https://issues.apache.org/jira/browse/FELIX-2748
We need to think about this a little bit to see if there is an
alternative (more loose way) to achieve what was implemented in
FELIX-2748, because it is definitely necessary.

Hi everyone;
It seems that I can't stop anymore the framework from the Gogo shell, when
typing Ctrl-C ?
I'm using the following bundles, including latest web console:
g! lb
START LEVEL 1
ID|State |Level|Name
0|Active | 0|System Bundle (3.2.0)
1|Active | 1|Apache Felix Bundle Repository (1.6.2)
2|Active | 1|Apache Felix Configuration Admin Service (1.2.8)
3|Active | 1|Apache Felix Gogo Command (0.8.0)
4|Active | 1|Apache Felix Gogo Runtime (0.8.0)
5|Active | 1|Apache Felix Gogo Shell (0.8.0)
6|Active | 1|Apache Felix Http Jetty (2.2.0)
7|Active | 1|Apache Felix Log Service (1.0.1)
8|Active | 1|Apache Felix Metatype Service (1.0.4)
9|Active | 1|Apache Felix Shell Service (1.4.2)
10|Active | 1|Apache Felix Web Management Console (3.1.8)
And when I type "Ctrl-C", the shell is hanging, and does not exit.
In the following jstack dump (taken after having typed "Ctrl-C" on gogo
shell), jetty seems to be blocked while
stopping: (see the thread "Jetty HTTP Service") ?
