Switch "-Duser.dir" breaking the working dir for classpath argument

ADDITIONAL SYSTEM INFORMATION :
Windows 10
java version "1.8.0_301"
Java(TM) SE Runtime Environment (build 1.8.0_301-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.301-b09, mixed mode)



A DESCRIPTION OF THE PROBLEM :
The switch "-Duser.dir" doesn't set the working dir for the "-cp" argument and breaks it.
Using a relative path is sometimes necessary since only ANSI arguments are supported.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
For this file structure on Windows 10 :
    %APPDATA%\MyApp
        lib
          myapp.jar


This works:

    pushd "%APPDATA%\MyApp"
    java -cp "lib\*" myapp.Main


but this fails with a ClassNotFoundException when "user.dir" is set :

    pushd "%TEMP%"
    java -Duser.dir="%APPDATA%\MyApp" -cp "lib\*" myapp.Main


It also fails with a ClassNotFoundException with the correct working dir but a different "user.dir" :

    pushd "%APPDATA%\MyApp"
    java -Duser.dir="%TEMP%" -cp "lib\*" myapp.Main


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The switch "-Duser.dir" should either set the working dir for the classpath or not break it.
ACTUAL -
Not only "-Duser.dir" does not set the working folder for "-cp",
it also breaks the loading of classes when "-cp" contains a relative path.

FREQUENCY : always
