There is a clash between BeanInfos for two classes of the
same name in different packages (namely java.awt.TextArea
and org.apache.taglibs.input.TextArea) when placing the
BeanInfo into yet another package (namely
org.netbeans.modules.form.beaninfo.awt.TextAreaBeanInfo),
specified in the BeanInfo seach path. This by itself it
expected, since the way the JavaBeans spec is written,
Introspector has no way to figure out whether
TextAreaBeanInfo is BeanInfo for java.awt.TextArea or
org.apache.taglibs.input.TextArea.

However, if the BeanInfo specifies a BeanDescriptor:

    public BeanDescriptor getBeanDescriptor() {
	return new BeanDescriptor(java.awt.TextArea.class);
    }

then Introspector can figure out that this BeanInfo is
BeanInfo for java.awt.TextArea, and not for
org.apache.taglibs.input.TextArea.

The way it currently works, when looking for BeanInfo for
org.apache.taglibs.input.TextArea, Introspector finds this
class. The awkward thing is that

Introspector.getBeanInfo
(org.apache.taglibs.input.TextArea.class).getBeanDescriptor
().getBeanClass()

returns java.awt.TextArea.class. I believe the correct
behavior in the case that bi.getBeanDescriptor
().getBeanClass() returns non-null, should be that this
beaninfo is only found for this one bean class, and not for
other classes of the same name in different packages.


To reproduce:
1. Create two classes p1.Clazz and p2.Clazz with the same
name in different packages

2. Create a BeanInfo p3.ClazzBeanInfo which extends
SimpleBeanInfo, and its getBeanDescriptor() method returns
new BeanDescriptor(p1.Cl.class)

3. Put package p3 into Introspector's BeanInfo search path

4. Try

BeanInfo bi = Introspector.getBeanInfo(p2.Clazz.class);

Introspector will find p3.ClazzBeanInfo.

5. Try

Class c = bi.getBeanDescriptor().getBeanClass();

The returned class will be p1.Clazz



The following invariant should hold:

Introspector.getBeanInfo(clazz).getBeanDescriptor
().getBeanClass()

returns either null or clazz.
