-------------------------------------
Resolution: Fixed
Fix Version/s: 4.2.0
> Threads not stopped on karaf.restart + bundle(0).stop()
> -------------------------------------------------------
>
> Key: KARAF-5327
> URL: https://issues.apache.org/jira/browse/KARAF-5327
> Project: Karaf
> Issue Type: Bug
> Components: karaf-core
> Affects Versions: 4.2.0
> Reporter: Grzegorz Grzybek
> Assignee: Guillaume Nodet
> Fix For: 4.2.0
>
>
> I was looking at:
> {noformat}
> karaf@root()> system:property karaf.restart true
> karaf@root()> stop 0
> {noformat}
> I expected OSGi/Felix to be stopped, start-level go to 0 and all
> components/services/threads be stopped.
> However when Karaf came to:
> {noformat}
> "main@7301" prio=5 tid=0x1 nid=NA runnable
> java.lang.Thread.State: RUNNABLE
> at org.apache.karaf.main.Main.main(Main.java:170)
> {noformat}
> i.e., when Karaf decided to loop instead of System.exit() (because of
> karaf.restart=true), I saw the following threads remaining:
> * jline
> {noformat}
> "JLine terminal non blocking reader thread@7394" daemon prio=5 tid=0x5e
> nid=NA runnable
> java.lang.Thread.State: RUNNABLE
> at java.io.FileInputStream.readBytes(FileInputStream.java:-1)
> at java.io.FileInputStream.read(FileInputStream.java:255)
> at org.jline.utils.InputStreamReader.read(InputStreamReader.java:270)
> - locked <0x1ce3> (a java.io.FileInputStream)
> at org.jline.utils.InputStreamReader.read(InputStreamReader.java:200)
> at org.jline.utils.NonBlockingReader.run(NonBlockingReader.java:276)
> at java.lang.Thread.run(Thread.java:748)
> {noformat}
> * shutdown socket thread
> {noformat}
> "Karaf Shutdown Socket Thread@7393" daemon prio=5 tid=0x18 nid=NA runnable
> java.lang.Thread.State: RUNNABLE
> at java.net.PlainSocketImpl.socketAccept(PlainSocketImpl.java:-1)
> at
> java.net.AbstractPlainSocketImpl.accept(AbstractPlainSocketImpl.java:409)
> at java.net.ServerSocket.implAccept(ServerSocket.java:545)
> at java.net.ServerSocket.accept(ServerSocket.java:513)
> at
> org.apache.karaf.main.ShutdownSocketThread.run(ShutdownSocketThread.java:57)
> {noformat}
> (In fabric8v1 I also saw jetty threads running, but it's pax-web fault).
