[eclipse-clp-users] OutOfProcessEclipse and Linux

My OutOfProcessEclipse parallelisation works now (thanks to Wit Jakuczun 
and Joachim Schimpf) .. but only in Windows.
When porting the program to linux, i get the following error:

java.lang.NumberFormatException: null
         at java.lang.Integer.parseInt(Unknown Source)
         at java.lang.Integer.parseInt(Unknown Source)
         at 
com.parctechnologies.eclipse.OutOfProcessEclipse.<init>(OutOfProcessEclipse.java:82)

called by

         System.setProperty("eclipse.directory", ECLIPSE_DIR);

         eclipseEngineOptions = new EclipseEngineOptions();
         eclipseEngineOptions.setUseQueues(false);
         eclipseEngineOptions.setGlobalSize(64);
         eclipseEngineOptions.setLocalSize(64);

         // Initialise Eclipse
         try {
             eclipse = new OutOfProcessEclipse(eclipseEngineOptions); 
//ERROR
             System.out.println("Compiling \""+ECLIPSE_SOURCE_DIR+"\"");
             eclipse.compile(new File(ECLIPSE_SOURCE_DIR));
             eclipse.rpc("use_module(prolog_reasoner)");

         } catch (EclipseException e) {
             // TODO Auto-generated catch block
             e.printStackTrace();
         } catch (IOException e) {
             // TODO Auto-generated catch block
             e.printStackTrace();
         }

When looking into the eclipse clp source code, the relevant lines are:

75 	// Read the port number from the eclipseProcess' stdout
76 	String portString = eclipseProcessStdout.readLine();


81 	// make port string into an int
82 	int port = Integer.parseInt(portString);


Exactly the same init with Embedded Eclipse works. I also tried 
reinstalling eclispe clp and updated it to the latest ftp version (150).

best regards Christian Wirth
