FULL PRODUCT VERSION :

A DESCRIPTION OF THE PROBLEM :
javapackager.exe cannot be launched on Windows (in all but one case, see steps to reproduce). This is problematic, because build tools like Maven typically use absolute paths to refer to JDK tools, which currently doesn't work.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
in Command Prompt:
> "C:\Program Files\Java\jdk-9\bin\javapackager.exe" -help
> cd "C:\Program Files\Java\jdk-9\bin"
> .\javapackager.exe -help
> javapackager.exe -help

in Windows PowerShell:
> & "C:\Program Files\Java\jdk-9\bin\javapackager.exe" -help
> cd "C:\Program Files\Java\jdk-9\bin"
> .\javapackager.exe -help
> javapackager.exe -help


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
all 6 javapackager commands succeed and show its help
ACTUAL -
only the last javapackager command succeeds and shows its help

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Unrecognized option: -m
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

REPRODUCIBILITY :
This bug can be reproduced always.
