java - Sonar dead store to local variable -

i have following code , sonar telling me following error message:

dead store descriptions1 in new com.dscsag.dsct2c.test.teststep(integer, string, model) 

in follwing code:

for (integer count = 0; count < teststepcount; count++)     {       if (xmlreader.istestexistingforordernumber(count, ordernumber, version))       {         if (xmlreader.checkforduplicatetest(ordernumber, count, version))         {           globalvariables.logging_logger.error("### " + this.getclass().getsimplename()               + ": there 1 or more duplicated order numbers test " + count + " under test step " + ordernumber + ".");           model.setstatustext("status_duplicated_test", ordernumber.tostring(), statuscode.error);           throw new exception();         }         else         {           globalvariables.logging_logger.info("### " + this.getclass().getsimplename() + ": no duplicated found test " + count               + " under test step " + ordernumber + ".");           boolean functionneeded = xmlreader.isfunctionneededforordernumber(ordernumber, count, version);            string[][] descriptions1 = new string[2][descriptions[0].length];            (int = 0; < this.descriptions[0].length; a++)           {             descriptions1[0][a] = descriptions[0][a];             descriptions1[1][a] = xmlreader.gettestdescription(descriptions[0][a], ordernumber, count, version);           }            arraylist<string> filesstring = xmlreader.gettestfilesforordernumber(ordernumber, count, version);           arraylist<file> filesfile = new arraylist<file>();           iterator<string> = filesstring.iterator();           while (it.hasnext())           {             file file = new file(globalvariables.path_testfiles                 + xmlreader.getvaluedocumentconfiguration(xmlelements.cad_appl, xmlelements.testing_environment, null) + "/" + it.next());             filesfile.add(file);              globalvariables.logging_logger.info("### " + this.getclass().getsimplename() + ": added file test " + count                 + " under test step " + ordernumber + ": \"" + file.getname() + "\"");           }            testobjectslist.add(new testobject(functionneeded, xmlreader.getfunctionnameforordernumber(ordernumber, count, version),               descriptions1, filesfile));            globalvariables.logging_logger.info("### " + this.getclass().getsimplename() + ": created test object test " + count               + " under test step " + ordernumber + ".");         }       }       else       {         model.setstatustext("status_no_test", count.tostring(), statuscode.warning);       }     }   } 

can see why store "dead" descriptions1? think have use variable.

its false positive of sonar. sonar works on compiled code, not source. guess access descriptions1 optimized away or replaced compiler, sonar cant see it.
