             Summary: Line breaks in base64binary cause a validation error
                 Key: XMLBEANS-599
                 URL: https://issues.apache.org/jira/browse/XMLBEANS-599
             Project: XMLBeans
          Issue Type: Bug
    Affects Versions: Version 5.0.3
            Reporter: Daniel Hengst


When trying to migrate from XmlBeans 3.1.0 to 5.0.3 the following issue caused some unit tests to fail:
 
The XML data contains elements of type base64binary which have line breaks.
Validation via XmlObject.validate() now returns an error:
"error: base64Binary: Invalid value: not encoded properly".

The error originates from the class org.apache.xmlbeans.impl.values.JavaBase64Holder:
{code:java}
    public static byte[] lex(String v, ValidationContext c) {
        try {
            return Base64.getDecoder().decode(v);
        } catch (IllegalArgumentException var3) {
            c.invalid("base64Binary", new Object[]{"not encoded properly"});
            return null;
        }
    }
{code}
The decode call fails with an IllegalArgumentException "Illegal base64 character 20".
(It's character 20 because XmlBeans converts the line break to a space in XmlWhitespace.collapse().)

The definition of the base64binary type allows for the presence of whitespace
[https://www.w3.org/TR/xmlschema-2/#base64Binary]

Therefore I'd suggest to change the Base64 call as follows:
{code:java}
Base64.getMimeDecoder().decode(v);
{code}
