Hi,
I'm having the same problem here, although not directly through AndroMDA, but
through a self-written bit of code... My locale is english though, so the
problem might lie elsewhere...
I've based the piece of code on the AndroMDA sources though, and the static {}
codeblock, which sets some system properties relating to MDR, seems to be
indirectly responsible...
I've posted the following mail to the MDR users mailing list... Those
interested in the problem might want to follow it up there...
Cheers,
Hans
