Batch scripts should show some error message when we set JAVA_HOME to nonexisting folder

steps to reproduce:
...

jboss-eap-6.0\bin>set JAVA_HOME=c:\dummy
jboss-eap-6.0\bin>standalone.bat
Calling "W:\tmp\pk\jboss-eap-6.0\bin\standalone.conf.bat"

>

...

batch script will end on this line (standalone.bat)
l:73 "%JAVA%" -client -version 2>&1 | findstr /I /C:"Client VM" > nul

On linux we get at least error message:
./standalone.sh: line 178: /home/dummy/bin/java: No such file or directory
