   Preondition Violations
   Expression super.testStandaloneCR() is a method call throwing exception(s) that should be caught by a try block that will be extracted
   Expression addPathElement(pathElements[i]) cannot be parameterized, because it has dependencies to/from statements that will be extracted
   Expression super.testStandaloneCR() is a void method call, and thus it cannot be parameterized
   Expression addPathElement(pathElements[i]) is a void method call, and thus it cannot be parameterized
