Hello,
I am getting a java error when using Elasticsearch-migrate. I realize this tool is deprecated and don't expect help.
To simplify the problem, I emptied the users file and created a single user, 'joe', with password 'joejoe' using the Elasticsearch-users tool (useradd mode), which worked fine:
# ls -l users
-rw-rw---- 1 root elasticsearch 65 Nov 13 16:56 users
# cat users
joe:$2a$08$m29sz92MBXNQsXttclp2dO6MlBQvgVyXUueGU.VdQ4xMgMdrxOuBO
.... Elasticsearch-migrate does not:
# elasticsearch-migrate native -u elastic -p XXXXX -U https://myhost:9200
Warning: The migrate tool is deprecated. Use the native realm directly instead of file realms.

The basic communication seems to work, since it does find the existing users.
The Elasticsearch log (/var/log/Elasticsearch.log) only shows this new entry:
[2021-11-13T16:56:36,318][INFO ][o.e.x.s.a.f.FileUserPasswdStore] [myhost] users file [/etc/elasticsearch/users] changed. updating users...

Am I missing something obvious?
