Re: [Jazzlib-developers] DBCS paths and file names not supported yet

[John L. <je...@pi...>]

Hello Eric

Thanks for finding these bugs and suggesting solutions.

I will apply these patches and make a new release of jazzlib soon, but
first I would like to create a test case that exposes this bug.

Could you send me a small zip file (and perhaps a few lines of Java
code) that I can use as a test case for this?

Thanks
John Leuner
