Some similar issues have been reported by the past (see ID 1811153 & 1706856), but I couldn't reproduce them. Since I don't have OS X Snow Leopard, I won't be able to reproduce this one either.
Do you have Eclipse error logs for this issue?.
I cannot install eclipse 3,5 on Mac OS X 10.4 so I won't be able to reproduce this bug unless this is reproducible on older eclipse versions.
What kind of "strange output" is it?.
