FULL PRODUCT VERSION :

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_02-b09)
Java HotSpot(TM) Client VM (build 1.5.0_02-b09, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :

A DESCRIPTION OF THE PROBLEM :
The following code is affected by the problem:

		XMLEncoder e = new XMLEncoder( System.out);
		URI uri = new URI("/foo/bar");
		e.writeObject( uri);
		e.close();

It results in the following error message and XML output:

java.lang.IllegalAccessException: Class java.beans.Statement can not access a member of class java.net.URI with modifiers "private"
Continuing ...
java.lang.Exception: discarding statement XMLEncoder0.writeObject(URI0);
Continuing ...
<?xml version="1.0" encoding="UTF-8"?>
<java version="1.4.2" class="java.beans.XMLDecoder">
</java>

The problem occurs, because the URI class does not provide a default constructor (which wouldn't make sense, since it's immutable).

The problem can be solved by providing an appropriate PersistenceDelegate. It would be nice, if that could be provided with a future JDK release. If not, please at least consider throwing an exception with a better error description.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Execute the supplied source code.

CUSTOMER SUBMITTED WORKAROUND :
Uncomment the e.setPersistenceDelegate line...
