Inconsistency in line break "{}" formatting in Java with in VS Code

In my VSC I have the extension called "Language support for java(TM) by red hat". The typical one that all of us who do Java have and this is self-evident. The formatter of said extension does not format correctly. Surely the formatting is taken from LLVM so there is some error or even some incorrect syntax when formatting

When I format in VSC this example code with java or java spring boot:

❌Incorrect - If I format like this, it leaves it like this
This happens on both the opening "{" and the ending "}". It seems that the extra space has no influence since the format accepts both together and extra spacing. When the correct one is the second one with the extra spacing.

Incorrect	Preview
❌
✅	Also say the formatting of the extension also leaves it like this if the code is like this.

3 incorrect formats accepted by the formatter have been shown. Therefore, if there is any code "in that format", the formatter will leave it that way. Only the correct one is the last one or the one made by Eclipse.
This doesn't make much sense since the code is stuck above or below or even between the curly braces "{}".

This way of formatting is not expected for those of us who work with Java. Eclipse does well in this regard.

✅ correct - This is how Eclipse does it. It doesn't matter how messy the code is. It will leave it like this:

Correct	Preview
✅

I have tried countless things, none of them worked.

This has worked since 2007 in eclipse. We are in 2024. As an example of a good format:

How do you solve this problem and get the correct form, like correct or equal to eclipse?

レポートの例とスクリーンショットを使って、Java VS Code extension における波括弧と改行のフォーマット動作を再現し、その後、出力を Eclipse と比較します。Extension の Java フォーマットのエントリーポイントから formatter の動作を追跡し、その差異が設定によるものか実装によるものかを判断します。報告されたレイアウトが期待される Eclipse 形式の結果に正規化されれば完了です。
