Anyone know why this has appeared in ClientSessionFactoryImpl:

 static
 {
 long value;
 try
 {
 // This system-variable is used on tests.
 value = Long.parseLong(System.getProperty("org.jboss.messaging.default-call-timeout", "30000"));
 }
 catch (Exception e)
 {

 // Security Managemen is probably in use on the VM
 value = 30000;
 }

 DEFAULT_CALL_TIMEOUT = value;
 }
