             Summary: Java thin client hungs on close
                 Key: IGNITE-18826
                 URL: https://issues.apache.org/jira/browse/IGNITE-18826
             Project: Ignite
          Issue Type: Bug
            Reporter: Nikita Amelchev
            Assignee: Nikita Amelchev
             Fix For: 2.15


There are several places where thin client threads can hang:

GridNioClientConnectionMultiplexer: SSL enabled + PA enabled
{noformat}
// Can return finished future with error -> sslHandshakeFut will not complete.
GridNioFuture<GridNioSession> sesFut = srv.createSession(ch, meta, false, null);

 if (sslHandshakeFut != null)
      sslHandshakeFut.get();
{noformat}

TcpClientChannel: PA enabled
{noformat}
ClientRequestFuture fut = new ClientRequestFuture(requestId, ClientOperation.HANDSHAKE);

 // TcpClientChannel may be closed and fut will not complete.
assert !closed.get();

pendingReqs.put(requestId, fut);
...
ByteBuffer buf = timeout > 0 ? fut.get(timeout) : fut.get();
{noformat}
