> J2SE documentation for java launcher [1] describes option -Xfuture:
> -Xfuture
> Perform strict class-file format checks. For purposes of backwards compatibility, the default format checks performed by the Java 2 SDK's virtual machine are no stricter than the checks performed by 1.1.x versions of the JDK software. The -Xfuture flag turns on stricter class-file format checks that enforce closer conformance to the class-file format specification. Developers are encouraged to use this flag when developing new code because the stricter checks will become the default in future releases of the Java application launcher.
> But DRLVM rejects this option:
> > java -Xfuture HelloWorld
> Unknown option -Xfuture
> Use java -help to get help on command line options
> Since developers are encouraged to use this option, this may prevents them from using Harmony/DRLVM in their work. It makes sense to enable this option in DRLVM.
