Play framework 2: Error when trying to start application in production mode

OS: Windows 7 64bit

java version: 1.7.0_17

javac Version: 1.7.0_17

I'm new to Play Framework, basically wanted to get a feel of everything.

There's a sample application called java/helloworld. Haven't changed anything and went on using the "start" command.


[helloworld] $ start

(Starting server. Type Ctrl+D to exit logs, the server will remain in background
)

Error occurred during initialization of VM

I don't think this is anything to do with Play. It seems like you have encountered [this issue](

), which looks to be a JVM bug on your flavour of Windows.

To run the sample applications in production mode, you may have to proceed as follows:

1. Run the `play stage` command (outside the Play console, just on the command line). The stage task is described [here](

)
2. Add [this JVM argument](

) to the `target\start` script generated by the stage task, before then starting the application.

As a workaround add

-Dfile.separator=\/

parameter to play.bat and build.bat.
