javadoc in 1.4.2 outputs incorrect html

javadoc in 1.4.2 generates incorrect html file which has incorrect link target.

REPRODUCE :
(1) Unfold the attached zip file, javadoc_test.zip
(2) Invoke go.bat in 1.4.2_0X

BEHAVIOR :
 Please see the api2/pkg2/Test21.html. This html file includes the following 3 incorrect
 link targets.
 
  a) http://test/api1/pkg1/sub1.Test12.html ( (1) in attached javadoc-link-diff.JPG)
  b) http://test/api1/pkg3/Test31.html ( (2) in attached javadoc-link-diff.JPG)
  c) http://test/api1/pkg3/sub3.Test32.html ( (2) in attached javadoc-link-diff.JPG)

 As to sub1.Test12.html in a) and sub3.Test32.html in c),
 those files are not created, but are set as link targets.
 
As to b), Test31.html is exist. However, this file is under ./api3/pkg3, but under ./api1/pkg3.

NOTE:
 This behavior seems to occur in 1.4.2, but in 1.4.1 and 5.0.
