Description

If I use following API call
JAXBUtils.nameToIdentifier("XML_Transfer",IdentifierType.CLASS)

It returns: XML_Transfer

But according to JAXB mapping algorithm,
it should return XMLTransfer

Expected:XMLTransfer
Actual: XML_Transfer

For API call "JAXBUtils.nameToIdentifier("xML_Transfer", IdentifierType.CLASS)".
It returns: XMLTransfer
Expected:XMLTransfer
Actual: XMLTransfer

Observations
There is a bug in the implementation of this method, it fails if element name starts with upper case and contains special character such as _.

It will also not work for any element name that starts with upper case and contains one of the following character in it.

• A hyphen ('-', \u002D, HYPHEN-MINUS),
• A period ('.', \u002E, FULL STOP),
• A colon (':', \u003A, COLON),
• An underscore ('_', \u005F, LOW LINE),
• A dot ('.', \u00B7, MIDDLE DOT),
• \u0387, GREEK ANO TELEIA,
• \u06DD, ARABIC END OF AYAH, or
• \u06DE, ARABIC START OF RUB EL HIZB.
