Re: [Jazzlib-developers] CRC errors using GZIPOutputStream

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

You seem to be a bit confused about the package names. 

Did you try using the classes in the net.sf.jazzlib namespace?

By using those we can remove the possibility of the problem being caused
by a mix of jazzlib and non-jazzlib code.

Can you send me the input file you used (so that I can reproduce this
bug)?

Thanks for using jazzlib and taking the time to report the bug
