Minecraft Server Start.bat 14w11b

When trying to start Minecraft server 14w11b with the start.bat using code "java -Xmx2G -Xms4G -jar minecraft_server.jar -o true
pause"

You get an "Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified"

I have 8GB of RAM install on the computer.

Code is edited (Have removed 14w11b from file)
