Hi Mandy,

Thanks for reviewing this, comments inlined.

I was being over-zealous, and trying not to rely on jvm.cfg, note that
jvm.cfg aliases -client to -server on 64-bit systems, I removed these
changes, as it does not add anything.

You are right this is an error, fixed.

The test runs on both j2sdk-image and JDK build, I use both
during development with the old infra/jdk7.

With the new infra I  use only images, because it is much faster now
to create images, also on Solaris images are mandatory, because
solaris symlinks exists only in the the images and there is a test
which checks for these in ExecutionEnvironment.java.
Note: these tests cannot be run on j2re-image as jtreg and the test itself
needs the compiler, downside of converting to java tests.

Right windows no arch directory,output below.
% find . -name jvm.dll
./j2re-image/bin/server/jvm.dll
./j2sdk-image/jre/bin/server/jvm.dll
./j2sdk-server-image/jre/bin/server/jvm.dll

*nixes do have arch directory (i386, amd64, ppc, etc).

A minor refactoring done.
