Sorry it would not. I am mixing multiple ideas. We need to be able to
both limit the amount of memory a jail can use (RCTL) but also ensure
applications don't think they use all of hw.physmem for building. This
may be actually adding a feature to limit how much memory jails can
think they have. The openjdk ports peer into hw.physmem and assume they
have a ton of memory and fail to build once they hit the limits we've
put in place via ulimit or rctl. Eclipse is probably doing something
similar regarding guessing how much memory it can use.

Do you have MAX_MEMORY set in poudriere.conf? This would cause the
openjdk ports to fail if it is largely different than how much memory
you actually have.
