When using ExecuteJava in other class, JVM don't allow to create streams.

[Alexey Mel'nikoff <al...@gmail.com>]

I try to create ant task which launch java in separate VM with
specified paramaters.
I try to execute class, which creates output and input streams.
When I did it in <java/> task, all works, but when I try to use it
in my task, streams are not created.
And class from lib can't work with files and user inputs.

There a part of my code:
