Summary

Obsolete the VM product option NewSizeThreadIncrease.

Problem

This option controls how much memory ergonomic generation sizing adds to the young generation per application thread when determining optimal size. Figuring out the right value for this option is challenging because there's no clear guidance on what number makes sense. This option only affects Serial GC potentially causing confusion leading to missed expectations.

Solution

Obsolete the VM product option NewSizeThreadIncrease without any deprecation period.
