If you're executing a batch file, then Cygwin is not involved at all
becaue CMD.EXE parses and executes batch files. So that's not the
problem.

The problem is that the ssh daemon starts with a clean (empty)
environment when setting up the session and only allows a certain
hardcoded list of allowed variables to be inherited. See
<http://cygwin.com/ml/cygwin/2006-11/msg00397.html>. This is a security
feature, so that it's impossible to accidently leak a variable from the
root session that started the daemon to the client session.
You should eliminate the batch file from the equation just to simpify
things; just ssh in and look at what environment variables are set, and
I think you will find that JAVA_HOME is simply not set. If you want it
to be set, you need to set it explicitly in the shell startup files
(/etc/profile, ~/.bash_profile, ~/.profile, etc.) as you would on *nix,
rather than letting it be inherited from the parent process or set by
the system.
