Local fix

Problem summary

• As to java.util.Properties.store(output, comments) method,
  according to Java Spec: If the comments argument is not null,
  then '#' character and a line separator are first written to the
  output stream. Thus, the comments can serve as an identifying
  comment. Any '\n', '\r' or "\r\n" in comments is replaced by a
  line separator generated by the Writer and if the next character
  in comments is not character # or character ! then an ASCII # is
  written out after that line separator.
  As to java.util.Properties.load(Reader) method,
  if there is a non-ASCII space character, just ignore it.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR9
  .
  The java.util.Properties.load(Reader) and store() method have
  been updated to prevent such a failure.
  .
  To obtain the fix:
  Install build 20100702 or later
