return STR."{\"success\":\"true\", \"message\":\"Switch \{enabled ? "ON" : "OFF"}!\"}";}}

Expected Result

        return STR."{\"success\":\"true\", \"message\":\"Switch \{enabled ? "ON" : "OFF"}!\"}";
    }
}

Additional Informations

If you need further information, please do not hesitate to contact me!

Reproduce the failure with the referenced Switch.java file and start at FormatterHandler.format, following the stack through DefaultCodeFormatter and TokenManager. The work is done when formatting the Java string-template example no longer raises IndexOutOfBoundsException and produces the expected indentation shown in the issue.
