Thanks. I'm able to recreate it. I should have a fix in trunk
shortly...maybe we'll roll a 3.2.1 release since this appears to be easy
to hit...even though our tests and the CT didn't catch it...
Thanks for reporting it.

Hi Richard,
Thank you for replying so quickly.
If you install fragment bundle before host-bundle, this error will occur
when we shutdown the framework.
This exception didn't kill the application, it just display a exception
stack message on console.

Hi guys,
After I upgrade felix framework from 3.0.9 to 3.2.0, I met an error like this:

org.apache.felix.framework.ModuleImpl.attachFragments(ModuleImpl.java:1183)

It seems that there is no Null checking when felix close a Module with
fragments. Here is the codes from ModuleImpl.java, line 1183.
List<Wire> hostWires = new ArrayList<Wire>(m_fragments.get(i).getWires());
It would be better to check whether getWires() return null before using it.
Thank you very much
