Minimal VM is built by specifying it as one of the jvm variants to 
configure eg:

./configure.sh --with-jvm-variants server,client,minimal1

note it is called minimal1 at the build level.

The Minimal VM is a variant of the client VM so only available for JIT 
supported platforms (not via Zero) and only for 32-bit.

If your JDK image has been built with the Minimal VM then it can be 
executed using "java -minimal ..."

Compact profiles are built by using "make profiles".
