Local fix

Problem summary

• java.uti.TreeMap's put and putAll method use its own public API
  which may be extended by sub-class. That may introduce a
  infinite loop.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR4
  .
  Replacing all public API callings internally with private method
  can address this issue.
  .
  To obtain the fix:
  Install build 20090117 or later
