A DESCRIPTION OF THE PROBLEM :
When unmarshalling the following fragment:

<dateTime>2007-04-26T11:51:08.0000000Z</dateTime>

we get a XMLGregorianCalendar object. If we invoke the toString() method on the object we get the following:

2007-04-26T11:51:08E-7Z, which is not a properly formatted string.

We get the same format error when marshalling the object, and unmarshalling that string gives null as a result.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The code:

String s = DatatypeFactory.newInstance().newXMLGregorianCalendar("2007-04-26T11:51:08.0000000Z").toString();
DatatypeFactory.newInstance().newXMLGregorianCalendar(s);

Produces the following output:

java.lang.IllegalArgumentException: 2007-04-26T11:51:08E-7Z
at com.sun.org.apache.xerces.internal.jaxp.datatype.XMLGregorianCalendarImpl$Parser.parse(XMLGregorianCalendarImpl.java:2787)
at com.sun.org.apache.xerces.internal.jaxp.datatype.XMLGregorianCalendarImpl.<init>(XMLGregorianCalendarImpl.java:433)
at com.sun.org.apache.xerces.internal.jaxp.datatype.DatatypeFactoryImpl.newXMLGregorianCalendar(DatatypeFactoryImpl.java:230)


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I would expect that java would be able to handle a valid xml dataTime element correctly.
ACTUAL -
Our application was processing data correctly with xml-documents coming from a JAXB environment, but was unable to process similar data produced by an application developed within a Microsoft environment by another company.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
See above

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
As a workaround we use the setMillisecond(getMillisecond()) methods to round to the nearest millisecond.

    XMLGregorianCalendar calendar = DatatypeFactory.newInstance().newXMLGregorianCalendar("2007-04-26T11:51:08.0000000Z");
    calendar.setMillisecond(calendar.getMillisecond());
    String s = calendar.toString();
    DatatypeFactory.newInstance().newXMLGregorianCalendar(s);
