Hi,
I wonder if it's a good idea to run the tests in test/jdk/sun/util/calendar/zi in advance...

[gnu-andrew]

I've revoked approval until there is evidence of sufficient testing.

make run-test TEST="jtreg:java/text/Format java/util/TimeZone sun/util/calendar sun/util/resources"

[gnu-andrew]

Confirmed clean but needs further testing

[xiezhaokun]

I've revoked approval until there is evidence of sufficient testing.

make run-test TEST="jtreg:java/text/Format java/util/TimeZone sun/util/calendar sun/util/resources"

I have executed the test cases, and there are no new failed test cases compared to the master branch.

[GoeLin]

Hi @xiezhaokun
please

• check the failed GHA action test
• Run the jtreg tests you were asked for
• Give a useful approval request comment. See also https://wiki.openjdk.org/spaces/JDKUpdates/pages/42598906/How+to+contribute+or+backport+a+fix, especially point 6. The current comment makes no sense for this issue, as it is not a bug.
  You can just issue the /approval comman again with a better comment.

[GoeLin]

Hi @xiezhaokun

I appreciate a lot you did all these backports.
Please continue working on them, these should all go into the April update.

Best, Goetz.

[gnu-andrew]

I'm at a loss on the GHA failures. Why is testing being run in things like the arm cross compile?

Test selection 'java/text/Format java/util/TimeZone sun/util/calendar sun/util/resources', will run:
* jtreg:test/jdk/java/text/Format
* jtreg:test/jdk/java/util/TimeZone
* jtreg:test/jdk/sun/util/calendar
* jtreg:test/jdk/sun/util/resources

It's failing because JTreg is not available there (it is installed by test.yml)

[gnu-andrew]

I merged this branch with the latest 21u-dev and pushed it to my own fork. Let's see what the fresh GitHub Actions run shows: https://github.com/gnu-andrew/jdk21u-dev/actions/runs/21755824628

[gnu-andrew]

Patch is clean, and requested testing and my own GHA testing shows no regressions. I'm happy for this to go in.
