Re: Java 22 is GA + Heads-up!
Hello David, I ran our Ant testsuite against Java 22 build 22+36-2370 and Java 23 EA build 23-ea+17-1368. The tests completed fine and no regressions or issues were found: https://ci-builds.apache.org/job/Ant/job/Ant%20Master%20Linux%20(latest%20EA%20JDK)/48/ https://ci-builds.apache.org/job/Ant/job/Ant%20Master%20Linux%20(latest%20EA%20JDK)/49/ -Jaikiran On 02/04/24 12:53 pm, David Delabassee wrote: Welcome to the latest OpenJDK Quality Outreach update!
