[cp-patches] FYI: JComponent fixlet

[Roman Kennke]

I fixed the putClientProperty method, so that if a null value is 
specified, the corresponding key is removed from the Hashtable. 
Otherwise we would get a NPE here.

       * javax/swing/JComponent.java
       (putClientProperty): If value == null, remove the key from the
       Hashtable, otherwise we would get an NPE here.
