Re: [equinox-dev] normalized jar

[Andrew Niefer <aniefer@xxxxxxxxxx>]

The contents of the jar should be bit-wise
the same, so the only difference between pre & post pack (for a previously
conditioned jar), if any, would be in the format of the jar itself.  Differences
could be, for example, in size & crc information for a given zip entry
appearing before or after the entry itself.  I'm not sure that these
differences would amount to a size difference for the jar.

In the case of nested jars which are
checked against their containers, we do need the jars to be bitwise the
same even in jar format.  For this reason, the jarProcessor in eclipse
does an additional "normalization" step which is different from
the pack200 -repack conditioning.

If you are getting differences after
unpack, you may not actually be using pack200 conditioned/normalized jars,
or something went wrong in that -repack  normalization step.

Should the size of the jar ( Normalized and signed jar
) be the same pre-packand post-unpack ?
