I try to start an JavaFx application via testexec from Xubuntu on a VirtualBox Host.

First I've started the autagent on port 60001
./autagent -p 60001


Then the test:
./testexec -project V9_Tests -version 1.0 -testsuite V9_Tests -server localhost -port 60001 -autconfig aut_v9client@localhost -resultdir "/home/danny/jubula_8.3.0.122/examples/testresults" -dbscheme "Default Embedded (H2)" -dbuser sa -dbpw ""
9/13/16 11:01:40 AM - AUT Agent:	Connecting to "localhost:60001" ...
9/13/16 11:01:40 AM - AUT Agent:	connection established.
9/13/16 11:01:41 AM - Database:	Connecting as "sa" to "jdbc:h2:~/.jubula/database/embedded;MVCC=TRUE;AUTO_SERVER=TRUE;DB_CLOSE_ON_EXIT=FALSE"...
9/13/16 11:01:45 AM - Database:	Connection established.
9/13/16 11:01:45 AM - Database:	Loading project "V9_Tests" in version "1.0"...
9/13/16 11:01:46 AM - Database:	Project loading completed.
9/13/16 11:01:46 AM - Project:	Checking completeness

9/13/16 11:01:46 AM - ... passed.
9/13/16 11:01:46 AM - AUT:		Starting AUT: "aut_v9client" via configuration "aut_v9client@localhost"...
!!Error occurred !!
	the communication between client and aut server could not established - AUTServer could not start: Unknown AUTServer exit code: 31.

What can be the reason ?
Any ideas?
The application can be started manually without the autagent on that system.

Hi there,

thanks for the information. If you start the ITE on that system and try to start the AUT via the ITE, do you get the same error?

Best regards,
Alex

Hi Alexandra,

I tried that in the first place, but on this system I'm not able to open a test project in Eclipse, see Jubula on VirtualBox Linux (Xubuntu) - Endless Connecting to Database

However, I think that here at org.eclipse.jubula.rc.common.AUTServer.sendExitReason(AUTServer.java:702) a Null check is missing
protected void sendExitReason(String errorMessage, int exitCode) { 
        try {
            m_iteCommunicator.send(new AUTServerStateMessage(
                    exitCode, errorMessage));
        } catch (CommunicationException ce) {
            log.error("Exception in start()", ce); //$NON-NLS-1$
        }
}


On other spots in this class, m_iteCommunicator is being checked against Null and here it isn't

see https://github.com/eclipse/jubula.core/blob/master/org.eclipse.jubula.rc.common/src/org/eclipse/jubula/rc/common/AUTServer.java

Hi Alex,

Yes, I see the same error in the eclipse environment on linux. As I said before I think, the NullPointerException should be avoided in the code.
