Dan,
It worked fine for me, but then it occurred to me I ought to try a Sun
JRE. That resulted in this
java.lang.NullPointerException
at javax.xml.datatype.Duration.getYears(Duration.java:256)
at
com.sun.org.apache.xerces.internal.jaxp.datatype.DurationImp l.compare(DurationImpl.java:875)
at javax.xml.datatype.Duration.equals(Duration.java:872)
at
org.eclipse.emf.ecore.xml.type.internal.XMLDuration.equals(X MLDuration.java:128)
Looking at Duration's getYear implementation:
public int getYears() {
return getField(DatatypeConstants.YEARS).intValue();
}
and then considering that getField is defined to return null
/**
* Gets the value of a field.
*
* @return
* If the specified field is present, this method returns
* a non-null non-negative {@link Number} object that
* represents its value. *If it is not present, return null.*
* For YEARS, MONTHS, DAYS, HOURS, and MINUTES, this method
* returns a {@link java.math.BigInteger} object. For
SECONDS, this
* method returns a {@link java.math.BigDecimal}.
*/
public abstract Number getField(final DatatypeConstants.Field
field);
it's not surprising that we'd get a null pointer exception in getYears.
It's really a bug in the JRE, but if you open a bugzilla, and I put in
workaround code (overrides of getYears and related methods) in our
XMLDuration implementation. So please open a bugzilla. Note that it's
an issue that needs to be fixed in the EMF core runtime, so best to open
the bugzilla there.

Dan,
Intentionally bogus! :-P It would have been better to leave them
abstract if a conforming implementation of getField is going to result
in null pointer exceptions. Jeesh. The changes are committed for 2.4.2
and 2.5.0.

Dan,
What would I need to do to reproduce this problem myself?
