   Preondition Violations
   Unmatched statement remotedir=ftp.printWorkingDirectory(); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted

   Preondition Violations
   Unmatched statement result=(InputSource)resolveEntity.invoke(resolverImpl,new Object[]{publicId,systemId}); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted
   Unmatched statement result=(InputSource)resolveEntity.invoke(resolverImpl,new Object[]{publicId,systemId}); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted
