java formatter: unable to wrap/break long Strings

I come from Intellij idea and I'm used to break long lines with the formatter. I managed to export/import most of the settings, but I can not manage it that vscode breaks long String lines, splitting the Strings with "firstPart" + "secondPart".

These are my related settings in the codeFormatterSettings.json:

<setting id="org.eclipse.jdt.core.formatter.lineSplit" value="180"/>
<setting id="org.eclipse.jdt.core.formatter.formatter_wrap_long_strings" value="true"/>
<setting id="org.eclipse.jdt.core.formatter.wrap_strings" value="true"/>
<setting id="org.eclipse.jdt.core.formatter.wrap_before_string_concatenation" value="true"/>

Please ask if I should upload the whole file.

This is an example line of code:

String strSystemPrompt =
                "You are a system that generates a concise and informative answer in less than 100 words for the given question, which is marked with QUESTION. Use the given search results marked with SEARCH RESULT as only knowledge base. Answer questions in the language of the question, i.e. german questions in german and only english questions in english.";

This is the expected output:

String strSystemPrompt =
                "You are a system that generates a concise and informative answer in less than 100 words for the given question, which is marked with QUESTION. Use the given search" + 
                "results marked with SEARCH RESULT as only knowledge base. Answer questions in the language of the question, i.e. german questions in german and only english" + 
                "questions in english.";

Am I missing something, is it not supported, or is it a bug?

Beginne damit, das Verhalten des Formatters mit den in codeFormatterSettings.json gezeigten Einstellungen und dem Java-Beispiel aus dem Issue zu reproduzieren. Prüfe, ob die aufgeführten Optionen für lange Zeichenfolgen und Zeichenfolgenverkettungen den vom VS Code extension verwendeten Java-Formatter erreichen. Als erledigt gilt die Aufgabe, wenn lange Java-Zeichenfolgenliterale wie in der erwarteten Ausgabe in verkettete Zeichenfolgen aufgeteilt werden.
