The beaninfo editor hasn't been updated in quite a while.  It still has the 
problem where the properties are not sorted.  If you extend JLabel or such and 
add a few properties, then good luck finding what you're looking for.

Let me report a specific bug.  The editor doesn't pick up the Display Name and 
Short Description of properties in the inheritance tree.  So, for example, if 
you extend JLabel and use the beaninfo editor to tweak a few things, then you 
lose all the Display Names and Short Descriptions which are SO helpful in the 
properties of your bean.  Yuck.

While I'm rambling, let me also say that it would seem that the editor would 
do better using a JTable, rather than a JPanel of properties associated with a 
long list of entries.
