There is difference between doing
"jar xvf data.jar data" and "jar xvf data.jar"
you can also use zipinfo -v to check CEN entries.

If the previous one works, it means the zip file should have the healthy end table there (it goes down to end->cen-> loc->data file). The later goes from the sequential looking up from the beginning, so it only looks into the "loc" table, it may extract the file out even there is no cen and end tables. I thought you just did "java xvf data.jar" in your previous email. -Sherman

As per original email, yes I can. Also md5sum checks out. But large files result in a malformed zip file. -aps
