Unable to inject a URI with a fragment as a bean property value [SPR-7083]

If I create a bean with a property of type java.net.URI, and try to initialize it in an XML bean definition file, I'm unable to define a URI instance with a fragment in it.

For example, consider the following bean definition

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

	<bean id="bean" class="TestInitURI">
		<property name="uriSpec" value="env://server#3" />
		<property name="uri" value="env://server#3" />
	</bean>
</beans>

I apply this bean definition using the following test program:

import java.net.URI;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;

public class TestInitURI {

    private String uriSpec;
    private URI uri;

    public void setUri(URI uri) { this.uri = uri; }
    public void setUriSpec(String uriSpec) { this.uriSpec = uriSpec; }

    public static void main(String[] args) {
        BeanFactory beanFactory = new XmlBeanFactory(new ClassPathResource("beans.xml"));
        TestInitURI bean = beanFactory.getBean(TestInitURI.class);
        show("Bean property", bean.uri);
        show("Expected ", URI.create(bean.uriSpec));
    }

    private static void show(String prefix, URI uri) {
        System.out.println(prefix + " URI " + uri + " (host=" + uri.getHost() + ", authority=" + uri.getAuthority() + ", path="
                + uri.getPath() + ", fragment=" + uri.getFragment() + ")");
    }
}

The output is the following:

Bean property URI env://server%233 (host=null, authority=server#3, path=, fragment=null)
Expected  URI env://server#3 (host=server, authority=server, path=, fragment=3)

In other words, I would expect that defining a URI property in an XML bean definition file with a string constant is equivalent to initializing that property with a URI created by invoking URI.create(String) with the same string constant.

Good catch - fixed for 3.0.3!

Will be available in tonight's 3.0.3 snapshot. Feel free to give it an early try...
