Should be fixed now, please verify with a nightly build of 2005-02-19 or later.

Kev, your patch would miss files with a compressed size > 2GB.

The field inside of a ZIP local or central file header is four bytes long, so 
the
ZIP format can't store files larger than 4GB itself.

Nice catch, so the patch is ok for current API ! Sorry, didn't go far enough in 
the docs...

Hmm, I suppose so.
Just reading the docs...

setSize

public void setSize(long size)

Sets the uncompressed size of the entry data.

Parameters:
size - the uncompressed size in bytes 
Throws:
IllegalArgumentException - if the specified size is less than 0 or
greater than 0x bytes
See Also:
getSize()

The ZipEntry class doesn't support sizes larger than 4Gb ( -> Dec), so
the patch will provide support for files upto this limit imposed by the API, but
not larger files.

Well i thought of the same patch, but then you'll have the same bug for files 
larger then 4GB :(
The size won't be negative, but won't be the good neither, no ?

Created an attachment (id=14139)
 --> (http://issues.apache.org/bugzilla/attachment.cgi?id=14139&action=view)
Overrides ZipEntry.setSize() to check value of input

When the value is negative, assumes that the call to deflator has wrapped round
(32bit precision error) and converts the value into a meaningful long.
