-------------------------------------
It turned out that the client part of my code was ill-configured. After fixing
it I could make it work.
Sorry for hijacking this issue...
> SSLHandler calling wrap method after closeOutBound() on SSLEngine
> -----------------------------------------------------------------

> Key: DIRMINA-1082
> URL: https://issues.apache.org/jira/browse/DIRMINA-1082

> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.16
> Reporter: Kamal Rathod
> Assignee: Emmanuel Lécharny
> Priority: Major

> Hi,
> I am trying to connect through SSL and Proxy and getting below error.
> _ERROR quickfix.mina.initiator.InitiatorIoHandler - Socket :
> javax.net.ssl.SSLException: Improper close state: Status = OK HandshakeStatus
> = NEED_WRAP_
> _bytesConsumed = 0 bytesProduced = 87_
> _javax.net.ssl.SSLException: Improper close state: Status = OK
> HandshakeStatus = NEED_WRAP_
> _bytesConsumed = 0 bytesProduced = 87_

> I had a look at closeOutBound() method of SslHandler.java and suspect bug
> there.
> Line 484: sslEngine.closeOutBound()
> Line 490: sslEngine.wrap(emptyBuffer.buf(), outNetBuffer.buf());
>
> In the scenario the sslEngine is closed first and then the wrap method is
> called.
> As per java docs:
> _In all cases, closure handshake messages are generated by the engine, and
> {{wrap()}} should be repeatedly called until the resulting
> {{SSLEngineResult}}'s status returns "CLOSED", or
> [{{isOutboundDone()}}|https://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLEngine.html#isOutboundDone()]
> returns true. All data obtained from the {{wrap()}} method should be sent to
> the peer._
> _[{{closeOutbound()}}|https://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLEngine.html#closeOutbound()]
> is used to signal the engine that the application will not be sending any
> more data._
> So as per docs, wrap should be called repeatedly and then closeOutbound()
> method, but in code its reverse, after closeOutbound wrap is called.
> Can someone please check and comment on this?
