If you do already have a GCC plus recent GCJ port for OpenVOS you could
use the approach that IcedTea took and bootstrap OpenJDK using the
existing libre-java toolchain based on GCC, GCJ, GNU Classpath and ECJ.
See http://icedtea.classpath.org/ and the people on
distro-pkg-dev at openjdk.java.net will most likely be happy to help out.
