[jsword-devel] Error unpacking zip which includes dir entries

[Martin Denham]

I have discovered that module unzipping is a little fussy about the zips.
 The current JSword code does not cope with directory entries in the zip
file.

Some times when I zip up a module the zip includes directory entries which
make the zip unpacking fail (at least on Android) with the following stack
trace:

I wonder if others have experienced this.

I recall having a lot of problems with some of the zips from the Xiphos
repo, but no problems with zips on the CrossWire repo and I wonder if this
could be the cause.

I have created an ant task to generate the module zip and noticed that I
needed the 'filesonly="true"' flag on the zip task without which unzipping
failed.
<zip destfile="${distribution.dir}/${module.zipfile}" filesonly="true">

I wondered if anybody else had encountered this before.
