Local fix

Problem summary

• This problem is caused when the method of getBeanDescritpor() of
  a explicit BeanInfo returns null, which causes Introspector
  fails to find properties correctly.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR9
  .
  The java.beans.Introspector has been updated to prevent such a
  problem to happen.
  .
  To obtain the fix:
  Install build 20100817 or later
