AW: Can't fork VM if option value contains space

[Bernd Eckenfels]

It us not meant as a solution for Windows. There is no useful semantics in the command parser of Windows, just dont use it for stuff like that. It should work on most shells (mac,linux)

having said that i somewhat wonder why the original syntax did not work on OSX, it should preserv blanks when passed on with the right process API and no "/bin/sh -c".

gruss
Bernd

Betreff: Re: Can't fork VM if option value contains space

The solution from Bernd with single quotes around entire property does not work (at least on Windows), because entire thing is passed as String:
    VM options: '-Dmy.prop=A B C'
Note also that double quotes are gone.

@Aleksey:
- Original issue described is reproducible on Windows and Mac OS X. Try to pass property via -jvmArgs instead of passing it directly to java launcher.
- Quoting the quotes, i.e.:
    -jvmArgs -Dmy.prop="\"A B C\""
Works on Windows but fails on Mac OS X.
- Using runner API just works. :)

Best regards,
Dmitry
