Re: Can Dava decompile these classes?

["Ruijie Wang" <rjwang@cs.cornell.edu>]

I'm using ant 1.6.1 which I downloaded from the webpage.
Below is some output with -v option. Is it because java 1.3.1 does not
support regurlar expression?

For the past year, nobody has been working on Dava. We now have Nomair
starting to work on it again, and one of the things he plans to do is to
look into all the Dava bugs that were reported over the past year,
including yours.

I've never seen an error message like this. It seems like it could have
something to do with your ant installation. Are you using the ant that
comes with cygwin? What happens if you run ant with the -v switch?
