Java formatter ignores org.eclipse.jdt.core.formatter.tabulation.size and uses editor's 'tab size' when calculating line split

Java formatter ignores org.eclipse.jdt.core.formatter.tabulation.size and uses editor's 'tab size' when calculating how lines should be split. This makes it difficult for users to use their preferred indentation size without throwing off source control history diffs.

Environment

• JDK version: openjdk version "17.0.10" 2024-01-16 LTS
• Visual Studio Code version: 1.86.2
• Java extension version: 1.28.1

Steps To Reproduce

Relevant settings:

• Java formatter <setting id="org.eclipse.jdt.core.formatter.lineSplit" value="120"/> and <setting id="org.eclipse.jdt.core.formatter.tabulation.size" value="4"/> in my java formatter
  (full formatting file: java-formatter.xml.txt))
• VS Code set to tab size: 4

If I have a line that is 121 characters, the formatter will wrap appropriately. However, if someone else has their tab size:2, the total line length is calculated to be less than 120, and thus will unwrap the lines wich throws off the file history diffs.

Current Result

Line split is calculated based on VS Code's tab size setting, instead of the formatter's tabulation.size

Expected Result

Line split should be calculated based on the tabulation.size setting, to allow users to have their preferred tab size within VS Code

Beginne damit, das Verhalten des Formatierers mit den vorgegebenen Einstellungen für lineSplit und tabulation.size zu reproduzieren, wobei die Tabulatorgröße von VS Code variiert wird. Verfolge, wo die Zeilenlänge des Java-Formatierers berechnet wird, und überprüfe das Ergebnis anhand von Expected Result: Die Zeilenaufteilung sollte tabulation.size statt der Tabulatorgröße des Editors verwenden.
