Take a look at my answer to this question. Note 4 how you can use echoargs.exe to diagnose 3 these sort of problems. Most likely the 2 fix would be to quote the parameter e.g.:

java -jar "-Duser.language=en" any.jar

You 1 can test that using echoargs (from PowerShell Community Extensions):

echoargs -jar "-Duser.language=en" any.jar
Arg 0 is <-jar>
Arg 1 is <-Duser.language=en>
Arg 2 is <any.jar>

Using quotes works fine for me in PowerShell 4 on Windows 7.

java "-Dmy.property=value" -jar myjar.jar

Be careful: the jar name must 3 be placed right after -jar, and arguments placed 2 after -jar myjar.jar will be passed to the program inside the 1 jarFile.

Try launching instead using the following 14 pattern:

java -Duser.language=en -jar any.jar

That assumes that user.language 13 is meant as a system property. If you meant 12 it as a command line argument, change that 11 to:

java -jar any.jar -Duser.language=en

I am actually surprised that the command 10 line you mentioned works at all outside 9 of powershell (though I have confirmed that 8 it works fine for me too, even on Linux) and 7 it is also a little strange that things 6 would work differently inside and outside 5 of powershell.

From java -help:

Usage: java [-options] class [args...]                 
           (to execute a class)                        
   or  java [-options] -jar jarfile [args...]          
           (to execute a jar file)                     
where options include:
...
    -D<name>=<value>
                  set a system property
...

So basically you should 4 always put the JAR filename directly after 3 the -jar command line option, and any JVM options 2 (such as setting system properties with 1 -D) before.
