usejavacp = true with Scala 2.10

Hi all,

I have a problem porting ScalaLab with Scala 2.10:

when I use in Settings the usejavacp = true
it works within Netbeans correctly,
but when I run the executable standalone,
it outputs the error: "object scala not found"

In Scala 2.8 and Scala 2.9 the same code runs without problem,
without setting usejavacp=true

Can somebody identify what happens?

Regards
Stergios
