@prrace did you check how this change affects the performance, especially startup? I have experimented with Panama for littlecms: https://bugs.openjdk.org/browse/JDK-8313344 and found that the biggest issue is a cold start, 8 ms vs 100ms. An example of the report: https://jmh.morethan.io/?gists=4df0f27789cc4b0ca91fc5b2d677fe39,900b547e073cc1567971f46bfea151db
