使用Prowide解析含多个以$分隔的SWIFT MT940/MT950报文时输出不完整的问题求助

大家好，我最近在处理旧的SWIFT报文，重点是解析MT940和MT950类型的报文。目前遇到一个棘手的问题：我的单个报文文件里可能包含多个不同类型的SWIFT报文，它们之间用$符号分隔，但用Prowide-core库解析时，输出的结果不完整，只获取到了第一个报文的部分内容；而用swift-parser-py工具解析同一个文件，却能正确得到完整的MT950报文数据。

下面是我的相关测试内容，麻烦各位帮忙分析一下问题所在：

我编写的SwiftDemo.java代码 #

import com.prowidesoftware.swift.io.parser.SwiftParser;
import com.prowidesoftware.swift.model.SwiftMessage;

public class SwiftDemo {
    public static void main(String[] args) throws Exception {
        String path = "sample.txt";
        String fin = java.nio.file.Files.readString(java.nio.file.Paths.get(path), java.nio.charset.StandardCharsets.UTF_8);
        SwiftParser parser = new SwiftParser(fin);
        SwiftMessage sm = parser.message();
        System.out.println(sm.toJson());
    }
}

可以看到，Prowide只解析到了第一个以{1:F21...}开头的报文片段，而后面的MT950报文完全没有被解析出来；但python工具却正确识别到了完整的MT950内容。我是不是在使用Prowide的时候遗漏了什么步骤？比如没有处理多报文分隔符$的逻辑？还是Prowide需要特定的配置才能支持多报文文件的解析？

麻烦各位大佬指点一下，谢谢！
