Subject RE: filter copy corrupts jars?
Date Wed, 12 Jun 2002 23:13:06 GMT
That's a reasonable explanation, I suppose, but
does Java even have the notion of opening a file 
in binary or text mode?  Wonder if the native impls
are consistent in this regard.

| Unless I'm just tired, you should *never* copy any binary files with filtering turned on.
Even if it doesn't match any 
| tokens, it's still reading and writing as if it's text.
| 
| As I say, I could be wrong...
