Ian Boston commented on JAMES-1014:
-----------------------------------

With commit 951509

I still have the problem, connect with iMail connection doctor on OSX creates an open socked


dhcp-65:imap ieb$ lsof | grep 8143
Mail        297  ieb   32u    IPv6 0x0adac940        0t0      TCP localhost:55980->localhost:8143
(ESTABLISHED)
java      36786  ieb  400u    IPv6 0x0a5301f0        0t0      TCP localhost:8143->localhost:55980
(ESTABLISHED)
dhcp-65:imap ieb$ 


I then cause the OSGi bundle to reload causing destroy() to be invoked

Dispose IMAP Service

CPU goes to 100%

If I now tell iMail to take that imap connection off line, which should close the connection,
I get the remainder of the reload operation

>    Affects Versions: Trunk
>            Reporter: Ian Boston
>
> When I call destroy() on the AbstractAsyncServer ( from which the Imap Server extends)
open connections remain open and the server does not unload the component. I see that destroy
does try and tell the bootstrap to releaseExternalResource(), however if the imap client remains
connected, the client is not kicked off by the server.
> I am unloading a component from OSGi which then hangs forever. 
> It would probably be fine if the JVM terminated, as it would kill the established sockets.
