FULL PRODUCT VERSION :
java version "9-ea"
Java(TM) SE Runtime Environment (build 9-ea+144)
Java HotSpot(TM) 64-Bit Server VM (build 9-ea+144, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
java.exe shows the non existant option "--addmods". The correct option is currently "--add-modules".

(Sorry for possibly wrong category/subcategory... I couldn't find any that really fits)

If you can't reproduce it, maybe it is only in Germany.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
cd C:\Program Files\Java\jdk-9\bin
java

same with

C:\Program Files\Java\jre-9\bin
java


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
expecting something with "--add-modules", as this is the current syntax. "javac" shows the correct option:

  --add-modules <module>(,<module>)*
        Root modules to resolve in addition to the initial modules, or all modules
        on the module path if <module> is ALL-MODULE-PATH.
ACTUAL -
output:

...
    -addmods <modulename>[,<modulename>...]
                  Root-Module, die zusätzlich zum anfänglichen Modul aufgelöst werden sollen
....

REPRODUCIBILITY :
This bug can be reproduced always.
