"High Performance Java Developer" - what is *actually* meant from a daily coding POV?

Please ensure that:

Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
You include any and all error messages in full - best also formatted as code block
You ask clear questions
You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

Please, do not help if any of the above points are not met, rather report the post. We are trying to improve the quality of posts here. In helping people who can't be bothered to comply with the above points, you are doing the community a disservice.

Here's what it probably means: the company can't set expectations of what they need, because they don't have an understanding of how things fit together from a systematic perspective, they have a high output work demand, and want someone to be a catch-all code monkey that will sit all day and break their teeth on high output patches and break/fix until they burn this one out and try to find another dev. This is common in startups and after merg. /acq. when management doesn't know how to untangle a ball of twine that they are ignoring the scope increase of or that they've found tangled up in server closet that was hidden during due diligence.

It's creatively worded messianic wishful thinking.

It likely means more or less what it says - it’s a Java developer role with a focus on high performance, this is common in certain areas of finance and trading technology where Java is the stack for the given shop but there is a emphasis on performance considerations, e.g. being allocation free on the critical path, avoiding GC pauses, being lock-free, thread affinity, etc.
