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;
