Jar files identical (linux_x64)

[Erik Joelsson]

As of today, the jar files in the j2sdk image generated by the new build 
are identical to the old build on linux_x64. The only differing classes 
are the Version classes. From now on, we would like to keep it this way, 
so we can use the compareimage script as a baseline test for any changes 
we make.

Here are instructions for how to run the compareimage script.

First you need a reference build to compare against. You get this by 
building in the old way from the same source. Make sure you use Ant 
1.7.1 as newer ants add a bunch of empty package-info.class files which 
will confuse the output of compareimages.

When building using the new build system you need to run 'make images' 
to get the j2sdk and j2re images built.

When both are done building, comparing is done with:

common/bin/compareimage.sh build/linux-amd64/j2sdk-image/ 
build/linux-amd64-server-release/images/j2sdk-image/

For more information on how to use the script, see the documentation in 
the header comment in the script itself.

For reference, here is my current output:

erik at moya:/localhome/mercurial/build-infra-jdk8$ 
common/bin/compareimage.sh build/linux-amd64/j2sdk-image/ 
build/linux-amd64-server-release/images/j2sdk-image/
