I ran a large matrix of `DirectBufferAllocTest` configs on my 5950X overnight, and it did not fail once. Several GHA re-runs also came back clean. This gives me confidence current version works well.


#!/bin/bash

set -euxo pipefail

J=~/trunks/jdk/build/linux-x86_64-server-release/images/jdk/bin/java
JOPTS="-Xmx128m -Xlog:gc"

for T in 1 4 16 64 256 1024; do
for M in 1 2 4 8 16 32 64 128 256; do
  $J $JOPTS -XX:MaxDirectMemorySize=${M}m DirectBufferAllocTest.java -r 800 -t $T
done
done
