Play Framework - can not reserve enough space for object heap

问题

I made some modifications to my play project and when I try and run it I get errors.

>play run
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occured. Program will exit.

Is this a common problem? I am fairly inexperienced with the play framework but I have ran my project several times before without encountering this error.

Edit: Information regarding java version.

>java -version
java version "1.7.0_11"
Java(TM) Runtime Environment (build 1.7.0_11-b21)
Java HotSpot(TM) Client VM (build 23.6-b04, mixed mode, sharing)

In Play framework 2.0.3, <play framework install dir>\framework\build.bat script you need to replace the command line argument for the command below

java -Xms512M -Xmx1024M -Xss1M -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256M %DEBUG_PARAM% -Dfile.encoding=UTF8 -Dplay.version="%PLAY_VERSION%" -Dsbt.ivy.home="%~dp0..\repository" -Dplay.home="%~dp0." -Dsbt.boot.properties="file:///%p%sbt/sbt.boot.properties" -jar "%~dp0sbt\sbt-launch.jar" %*

into

java -XX:+CMSClassUnloadingEnabled %DEBUG_PARAM% -Dfile.encoding=UTF8 -Dplay.version="%PLAY_VERSION%" -Dsbt.ivy.home="%~dp0..\repository" -Dplay.home="%~dp0." -Dsbt.boot.properties="file:///%p%sbt/sbt.boot.properties" -jar "%~dp0sbt\sbt-launch.jar" %*

It solved my problem.
