Surly, thanks, JWells.
The question comes from(*maybe*) an issue:
https://java.net/jira/browse/GLASSFISH-20934
Here, there are two threads which all influence some module's state.
If I want to fix the issue, one way is that in
org.jvnet.hk2.osgiadapter.OSGiModuleImpl.start method, I catch the felix
exception and then, by some way, I get RunLevelControllerThread's
running result to see the bundle's status changing and re-start the
bundle(if needing).
"by some way" should be using listener, however, in reality, while GF
kernel is starting, it has registered an
listerner(com.sun.enterprise.v3.server.AppServerStartup.MasterRunLevelListener)
, and this listener is only limited in gf kernel scope. So, I am a
litter puzzled how to handle from osgiadapter module.
I am sorry for suddenly bringing the GF issue, if you have more time, I
want to listen your advice.
Thanks
Tang
