Apache Derby Eclipse Plugins Does not work if Eclipse installed in Windows path contaning spaces

I just installed Apache Derby Plugin on Eclipse Europa on Ubuntu and Windows and it work fine of both platforms.

Just want to report that if Eclipse placed on a path containing spaces like Program Files in windows, it fails at the time when we go to start the Derby Network Server after that we add the Derby nature to the project saying Class Not Found .

I think this is just a path related problem, if eclipse placed on path like C:\eclipse it works fine

Minor Nice to have a feature ..

Thanks
