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?

首先，使用 codeFormatterSettings.json 中显示的设置和 issue 中的 Java 示例重现 formatter 的行为。检查列出的长字符串和字符串拼接选项是否传递到了 VS Code extension 使用的 Java formatter。只有当长 Java 字符串字面量按预期输出所示拆分为拼接字符串时，才算完成。
