There might be different reasons why this parameter is not passed to the slave JVM: for example, it might have been declared final. Do you see the correct parameter in your job xml file (to be found in the JT UI or in the slave local FS)? You can also see the passed parameters if you do `ps aux` on the slave during the execution (but you need to catch the right time to catch the execution). -- Alex K
