How do I reliably prevent CDS archive generation during builds?

[Thomas Stüfe]

Hi,

is there a way to reliably prevent the jvm from being called with
-Xshare:dump during build?

Often, when I tinker with metaspace or compressed klass pointers, CDS gets
broken. During development, that is fine; it is a temporary state.

However, if -Xshare:dump is invoked, it may crash the JVM and break the
build.

I specified --disable-cds-archives and --disable-jvm-feature-link-time-opt.
But still, link time optimization step runs and calls the build JVM with
-Xshare:dump. Is that a bug?

Thanks, Thomas

P.S. Also, how is this handled for crossbuilds, where generating shared
archives on the build machine makes little sense?
