Nathan Beyer commented on HARMONY-6422:
---------------------------------------

Hmm ... a BeanDescriptor is defined as "global information", so it seems like it SHOULD record any changes, regardless of whether a new BeanDescriptor instance is returned each time.

> 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.
