Add shutdown hook to launcher to cleanly shutdown the framework is the process
is killed
----------------------------------------------------------------------------------------
Key: FELIX-1478
URL: https://issues.apache.org/jira/browse/FELIX-1478
Project: Felix
Issue Type: New Feature
Components: Main
Affects Versions: felix-1.8.1
Reporter: Richard S. Hall
Assignee: Richard S. Hall
Priority: Minor
Fix For: felix-2.0.0
As it stands currently (and dating back to the Oscar days), if someone does a
control-C, then the framework process just dies and there is no attempt to
shutdown cleanly. If we add a shutdown hook, then we can cleanly shutdown the
framework.
I am not sure if this would necessarily impact anyone who directly uses our
launcher to launch the framework. I imagine there could possibly be an issue if
someone uses our launcher, but registers their own shutdown hook. We also have
the potential issue of a deadlock or some situation where we cannot exit, which
could prevent the VM from exiting.
Any one have any thoughts?
