JCo nested context with independent stateful calls

Question

Hi experts,
is it possible to make independent nested stateful calls to two or more destinations?
The following sample code runs on a SAP WAS 7.10 and should visualize the problem:
     JCoDestination abapDest1 = JCoDestinationManager.getDestination("RFC_TEST");
     // Context 1     
     JCoContext.begin(abapDest1);
          JCoFunction incrementCounter1 = abapDest1.getRepository().getFunctionTemplate("Z_INCREMENT_COUNTER").getFunction();
          JCoFunction getCounter1 = abapDest1.getRepository().getFunctionTemplate("Z_GET_COUNTER").getFunction();            
          incrementCounter1.execute(abapDest1);
          incrementCounter1.execute(abapDest1);
          JCoDestination abapDest2 = JCoDestinationManager.getDestination("RFC_TEST");
          // Context 2          
          JCoContext.begin(abapDest2);
               JCoFunction incrementCounter2 = abapDest2.getRepository().getFunctionTemplate("Z_INCREMENT_COUNTER").getFunction();
               JCoFunction getCounter2 = abapDest2.getRepository().getFunctionTemplate("Z_GET_COUNTER").getFunction();            
               incrementCounter2.execute(abapDest2);
               incrementCounter2.execute(abapDest2);            
               incrementCounter2.execute(abapDest2);
               int remoteCounter = 0;
               getCounter1.execute(abapDest1);               
               remoteCounter = getCounter1.getExportParameterList().getInt("GET_VALUE");
               out.println("counter for 1=["+remoteCounter+"]");     // remoteCounter = 5
               getCounter2.execute(abapDest2);
               remoteCounter = 0;
               out.println("reset counter to ["+remoteCounter+"]");
               remoteCounter = getCounter2.getExportParameterList().getInt("GET_VALUE");
               out.println("counter for 2=["+remoteCounter+"]");     // remoteCounter = 5          
          JCoContext.end(abapDest1);
     JCoContext.end(abapDest2);
The intended output of the program is for the first counter 2 and the second counter 3 but both outputs are 5.
Does anyone knows this problem? Or is it not a problem just a feature of SAP context management to bind every context within one thread to one connection?
Best regards
Robert

Hi Robert,
You can first try stopping a Java application named sessionmgmtjcoapplib from Star&Stop, then register yours sessionReferenceProvider again.
