------------------------------------

             Summary: Conversion of data type CHAR and CHAR_OBJ to XML not valid for character

                 Key: OPENJPA-2362
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2362

         Environment: independent
            Reporter: Benno Huber


Saving data with char values below 0x20 will throw runtime execption next time should be retrieved
(Stack trace below).

Code for XMLFileHandler starting line 309 should be modified like this:

            case JavaTypes.CHAR:
            case JavaTypes.CHAR_OBJ:
                // quote chars so we can distinguish whitespace chars; special
                // case for \0
                char c = ((Character) val).charValue();
                out.write("'");
                // according to W3C spec (http://www.w3.org/TR/xml-entity-names/000.html)
                // no characters below 0x20 are allowed on document
                // execpt tab, lf and cr
                if (c <32)
                    out.write("0x" + Integer.toHexString((int)c));
                else
                    out.write(StringEscapeUtils.escapeXml(val.toString()));
                out.write("'");
                break;
