I have installed Elasticsearch for the first time and I am seeing msgs that a terminally deprecated method in java.lang.system has been called. Should I be concerned with this, even though it looks like Elasticsearch is started and running?
Please don't post images of text as they are hard to read, may not display correctly for everyone, and are not searchable.
Instead, paste the text and format it with </> icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer.
It would be great if you could update your post to solve this.
A terminally deprecated method in java.lang.System has been called System::setSecurityManager has been called by org.Elasticsearch.bootstrap.Elasticsearch (file: /usr/share/Elasticsearch/lib/Elasticsearch-7.15.1.jar) Please consider reporting this to the maintainers of org.Elasticsearch.bootstrap.Elasticsearch System::setSecurityManager will be removed in a future release
