RFR: 8345302: Building microbenchmarks require larger Java heap

Wed Dec 4 23:18:47 UTC 2024

Recently we have started to see OOME being thrown when building the microbenchmarks. See the bug for a closer analysis of why this happens by @shipilev and @mcimadamore. This patch just increases the default mx setting for the "big" java configuration in the build. I think that in 2024, we are ready to bump this to 2048M.

I'm not touching the 32 bit max mx setting as I have no way of testing it.
