   Preondition Violations
   Expression super.testUnixLineSeparator() is a method call throwing exception(s) that should be caught by a try block that will be extracted
   Expression super.testUnixLineSeparator() is a void method call, and thus it cannot be parameterized
   Expression managingTask.log(thread[i].toString(),Project.MSG_DEBUG) is a void method call, and thus it cannot be parameterized
