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

Commencez par reproduire le comportement du formateur avec les paramètres lineSplit et tabulation.size fournis, en faisant varier la taille des tabulations de VS Code. Suivez l’endroit où la longueur de ligne du formateur Java est calculée et vérifiez le résultat par rapport à Expected Result : le découpage des lignes doit utiliser tabulation.size plutôt que la taille des tabulations de l’éditeur.
