使用自定义java运行时映像（但不是不使用）时发生的javax.net.ssl.SSLHandShakeException

Question

我有这样一个类，它只是发送一个http post请求：

import java.net.*; import java.io.*;
public class JarRuntimeTest{
    public void start() throws Exception{
        HttpURLConnection connection = (HttpURLConnection) (new URL("https://google.com").openConnection());
        connection.setRequestMethod("POST");
        System.out.println(
        getResult((connection.getResponseCode() == HttpURLConnection.HTTP_OK)?
        connection.getInputStream():connection.getErrorStream()));
    }
    public String getResult(InputStream in) throws Exception{
        StringBuilder builder = new StringBuilder("");
        BufferedReader reader = new BufferedReader(new InputStreamReader(in));
        String line = null;
        while ((line = reader.readLine()) != null) builder.append(line);
        reader.close();
        return builder.toString();
    }
    public static void main(String[] args){try{new JarRuntimeTest().start();}catch(Exception e){e.printStackTrace();}}
}

我有这个.bat文件，它为它构建我的jar和java运行时映像，并使用这个自定义运行时映像来运行我的jar：

@echo off
javac JarRuntimeTest.java
jar --create --file thisismyjar.jar  --main-class JarRuntimeTest JarRuntimeTest.class
jdeps --list-deps thisismyjar.jar
jlink --add-modules java.base --output myruntime
myruntime\bin\java.exe -jar thisismyjar.jar
pause

正如@dave_thompson_085所说，必须包含jdk.crypto.ec。我不确定为什么JDEPS没有显示这一点。不管怎样，在我的jlink命令中包含它就起到了作用，而且它起作用了：

jlink --add-modules java.base,jdk.crypto.ec --output myruntime
myruntime\bin\java.exe -jar thisismyjar.jar
