Javadoc an enum under simplified chinese locale causes warning

FULL PRODUCT VERSION :
mustang b99

ADDITIONAL OS VERSION INFORMATION :
Linux localhost.localdomain 2.6.9-11.19WS

A DESCRIPTION OF THE PROBLEM :
javadoc an enum under simplified chinese locale. This problem can be reproduced by any java source files. The Warning message is:
@XX is an unknown tag. ( the message was in chinese.)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
javadoc any enum under simplified chinese locale.
This is the command of javadoc:
javadoc -protected -sourcepath "C:\FOP Wrapper\src" -encoding GB18030
-source 1.5 -d "C:\FOP Wrapper\javadoc" -charset GB18030 -docencoding
GB18030 "C:\FOP Wrapper\src\com\panda\report\common\CELLTYPE.java"

The "@return" tag in the resource file(doclets_zh_CN.properties) was translated into Chinese which I think should be remained English.....

in the j2se/src/share/classes/com/sun/tools/doclets/internal/tookit/resource/doclets_zh_CN.properties english version:
doclet.enum_values_doc=
...
...
@return an array containing the constants of this enum type,in \n...
chinese version:
@XXXXXXXXXXXXXXXXXXXXXXXXX(chinese characters)
even the "@return" was translated!

REPRODUCIBILITY :
This bug can be reproduced always.
