j2se\src\share\doc\jdk\fcs\LICENSE.rtf contains unknown characters that InstallShield displays as boxes. I can't paste the non-extended ASCSII characters here. I count 21 of them. Two of which are on either side of " PLEASE READ THE AGREEMENT CAREFULLY." in the first paragraph.

Wordpad ignores these characters, but StarSuite Writer and InstallShield do not.
Dito for file LICENSE_de.rtf.fcs this causes build failures when MILESTONE=fcs
