The spec for method
java.beans.beancontext.BeanContextSupport.add(Object targetChild)
does not specify behavior if 'targetChild' == null.
Currently method throws unexpected IllegalArgumentException.
More convenient behavior here is to throw NullPointerException
or else it should be figured in spec.
--------------The doc says:--------------
public boolean add(Object targetChild)

      Adds/nests a child within this BeanContext

      Invoked as a side effect of java.beans.Beans.instantiate().

      Parameters:
            targetChildren - The child objects to nest within this BeanContext

-----Here is the test demonstrating the bug:------
import java.beans.beancontext.*;
import java.beans.*;

public class Test {

    public static void main(String[] args) {

        BeanContextSupport bcs = new BeanContextSupport();
        try {
            bcs.add(null);
        } catch (Exception e) {
            System.out.println(e);
        }
    }
}
-----Output from test:--------------------
java.lang.IllegalArgumentException
--------------------------------------------------

Also the spec for method
java.beans.beancontext.BeanContextSupport.remove(Object targetChild)
does not specify behavior if 'targetChild' == null.
Currently remove(null) throws unexpected IllegalArgumentException too.
------The doc for remove says:-----------
public boolean remove(Object targetChild)
      Parameters:
            targetChildren - The child objects to remove
