How to skip "Creating CDS-NOCOOPS archive for jdk image for server"

[Thomas Stüfe]

Hi Oliver,

`--disable-cds-archive` disables CDS archive generation.

More generally, you can specify a different JVM for building purposes with
--with-build-jdk. This is different from --with-boot-jdk in that it has to
fit closely the target JVM - ideally, it has to be built from the same
sources. Specifying --with-build-jdk prevents the built JVM from being used
during building. Usually used for crossbuilds where the target VM won't run
on the build hardware.

So you could build a good JVM from the master branch and use that as build
jdk with your development branch, provided the branches are not too far off.

Cheers, Thomas
