This bug was introduced in Kestrel.

The constructor PropertyDescriptor(String propName, Class beanClass)
works wrong if beanClass does not contain getter.

JavaDoc says:
_____
Constructs a PropertyDescriptor for a property that follows the standard Java convention
by having getFoo and setFoo accessor methods.
          ^^^^^^^^^^^^^^^^^^^^^^^^^^
_____

So, it should throw IntrospectionException (JDK1.2.2), but it accepts wrong bean.

Here is an example to demonstrate this bug:

import java.beans.*;

public class Test01 {
    public static void main (String[] args) {
try {
PropertyDescriptor pd = new
PropertyDescriptor("noGetter",WrongBean.class);
} catch (IntrospectionException e) {
e.printStackTrace();
System.out.println("OKAY");
return;
}
System.out.println("Failed");
return;
    }
}

class WrongBean {
    int noGetter;
    public void setNoGetter (int noGetter) {
this.noGetter = noGetter;
    }
}

Here is output:
%java -fullversion
java full version "JDK-1.3-I"
%java Test01
Failed
%
%java -fullversion
java full version "JDK-1.2.2-U"
%java Test01
java.beans.IntrospectionException: No method "getNoGetter" with 0 arg(s)
        at java.beans.Introspector.findMethod(Introspector.java, Compiled Code)
        at java.beans.PropertyDescriptor.<init>(PropertyDescriptor.java, Compiled Code)
        at Test01.main(Test01.java, Compiled Code)
OKAY
