Re: jdk 1.6 bug or feature?

here is the compilable code from working app ( I could optimize per Lew
suggestion, I am sure there are better coding than this)

    public class CPA_argException extends Exception {
        String sArgName = "EFT_Originator_ID",
                sSz = "10";
        public CPA_argException(String argNm, String sz){
            sArgName = argNm;
            sSz = sz;
        }
        public @Override String getMessage (){
            return "CPAStd005Header argument exception - Invalid length
for "
                    .concat(sArgName).concat(", must be ").concat(sSz)+"
numeric digits only"; }
    };

 public HRecords(String EFT_Originator_ID /* 10 digit */,
            String FileCreationNumber /* sz=4*/, EFT_Format eft_driver)
            throws CPA_argException{
        sEFT_Originator_ID = EFT_Originator_ID;
        sFileCreationNumber = FileCreationNumber;
        eft_main = eft_driver;
        if (!((sEFT_Originator_ID.length() == 10)&
                (ieText.matchesPattern("[0-9]{10,10}",
EFT_Originator_ID)))){
                eft_main.showStatus("EFT_Originator_ID must be 10 numeric
digits only but we got "+EFT_Originator_ID.length() +" for the
value="+EFT_Originator_ID);
                throw new CPA_argException("EFT_Originator_ID","10");
            }
        try {int i = Integer.valueOf(EFT_Originator_ID);
        } catch(Exception e){CPA_argException ea2 = new
CPA_argException("FileCreationNumber","4");
                throw ea2;
            }

        if (!(FileCreationNumber.length()==4)) {
            eft_main.showStatus(
                "FileCreationNumber must be 4 numeric digits only but we got
"
                +FileCreationNumber.length() +" for the
value=<"+FileCreationNumber+">");
            CPA_argException ea2 = new
CPA_argException("FileCreationNumber","4");
                throw ea2;
            }
    } // constructor ends

//people will not be able to compile as the code reference a special library
ieText
// until they subst with a dummy connition
// it also ref another class edt_main

Iam abit rushed due to deadline,

hopefully I can later come back with a more simplistic standalone sample
code
