Re: JDK 16 is now in Rampdown Phase Two
Posted by Jaikiran Pai <ja...@apache.org>.
Hello Rory,
I ran the Ant testsuite on a Linux setup against this JDK 16 build
16-ea+32-2190. No issues were noticed. The regression that was observed
in the previous JDK 16 EA and was reported in
https://bugs.openjdk.java.net/browse/JDK-8258246, is no longer present
in this JDK 16 build.
As for the JDK 17 build 17-ea+5-266, the above reported regression
continues to exist in that build (I guess because the JDK16 repo changes
haven't yet been merged to JDK master repo or perhaps this JDK 17 build
is older). No other issues observed in this version.
The CI jobs are available for reference here:
JDK 16 -
https://ci-builds.apache.org/job/Ant/job/Ant%20Master%20(latest%20EA%20JDK)/jdk_axis=jdk16_ea,label_exp=ubuntu/64/
JDK 17 -
https://ci-builds.apache.org/job/Ant/job/Ant%20Master%20(latest%20EA%20JDK)/jdk_axis=jdk17_ea,label_exp=ubuntu/64/
