There is an old but still mostly correct instruction in
lang/openjdk8/bootstrap.mk. This assumes you already have a working
native toolchain though so that you can regenerate binaries with the
help of pkgsrc.

Bootstrapping for a new major version is a multi step process that
requires first building a JDK targeted to Linux w/ BSD patches so that
the Linux tools recognize BSD as a valid target. Then using that as
--with-build-jdk, cross compile to NetBSD with a build.sh toolchain
and prepared sysroot. The cross setup should be mostly per upstream's
documentation. Finally, copy jdk-image over to NetBSD host and follow
the instructions from bootstrap.mk to rebuild through pkgsrc.
