**Further info**

Data can be found in all of the aqa-test triage issues for the last few releases, like [this one](https://github.com/adoptium/aqa-tests/issues/6420).

Start with jdk/jshell/ExternalEditorTest.java, especially ExternalEditorTest.testAccept(), and reproduce the failure using the linked Grinder configuration on Alpine. Trace how editor.sh is created and launched, then confirm that ExternalEditorTest passes on Alpine without the reported Exec format error.
