> StandardBeanInfo behaves differently from RI GenericBeanInfo:
> -----cut here-------
> import java.beans.BeanInfo;
> import java.beans.Introspector;
> public class BeanTest {
> public static void main(String[] args) throws Exception {
> BeanInfo beanInfo = Introspector.getBeanInfo(BeanTest.class);
> System.out.println(beanInfo.getClass().getName()); // RI=GenericBeanInfo, Harmony=StandardBeanInfo
> System.out.println(beanInfo.getBeanDescriptor().getDisplayName()); // BeanTest (both)
> beanInfo.getBeanDescriptor().setDisplayName("test");
> System.out.println(beanInfo.getBeanDescriptor().getDisplayName());// test (RI) BeanTest (Harmony)
> }
> }
> -----cut here-------
> This is because the RI always returns the same instance from getBeanDescriptor() whereas Harmony returns a new instance.
> I don't know if this is a spec. violation or not, but the behaviour is different and unexpected, so should at least be documented in the BeanInfo Javadoc.
