JavaFX+MySQL程序自定义JRE运行失败，需排查依赖模块

我开发了一个基于JavaFX的小型应用，通过JDBC连接MySQL数据库。Jar包单独运行完全正常，但用launch4j打包成exe并搭配自己构建的精简JRE后，exe只能在装有完整JRE的环境下运行，用自定义JRE启动时会抛出通信链接失败的错误，具体日志如下：

[10-Jul-2023 15:40] FATAL - DbConnection.java - Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

我尝试用jdeps分析依赖：

jdeps --ignore-missing-deps --list-deps --multi-release 11 --module-path javafx\lib;libs --add-modules ALL-MODULE-PATH ExpensesViewer.jar

得到的依赖列表包含java.base、java.sql等模块以及多个JavaFX模块，但没检测到java.naming这类实际需要的模块。之后我用jlink构建自定义JRE：

jlink --no-header-files --no-man-pages --compress=2 --strip-debug --module-path libs;javafx/lib --add-modules java.base,java.naming,java.datatransfer,java.desktop,java.logging,java.management,java.net.http,java.scripting,java.sql,java.transaction.xa,java.xml,jdk.jsobject,jdk.unsupported,jdk.unsupported.desktop,jdk.xml.dom --output java-runtime

程序还是无法运行，直到我尝试添加所有可能的模块后才恢复正常，最终发现问题出在缺少jdk.crypto.cryptoki模块。

我从来没有直接使用过这个模块，想请教两个问题：

1. 我的程序为什么会依赖jdk.crypto.cryptoki模块？
2. 有没有更高效的方法排查这类隐式依赖问题？

附上我的module-info.java内容：

module ru.viewer.expensesviewer {
    requires javafx.controls;
    requires javafx.fxml;
    requires java.sql;
    requires mysql.connector.j;
    requires org.apache.logging.log4j;
    //requires rt;

    opens ru.viewer.expensesviewer to javafx.fxml;
    exports ru.viewer.expensesviewer;

    opens ru.viewer.expensesviewer.model to javafx.fxml;
    exports ru.viewer.expensesviewer.model;

    opens ru.viewer.expensesviewer.controller to javafx.fxml;
    exports ru.viewer.expensesviewer.controller;

    exports ru.viewer.expensesviewer.model.objects;
    opens ru.viewer.expensesviewer.model.objects to javafx.fxml;

    exports ru.viewer.expensesviewer.controller.settings;
    opens ru.viewer.expensesviewer.controller.settings to javafx.fxml;

    exports ru.viewer.expensesviewer.controller.reports;
    opens ru.viewer.expensesviewer.controller.reports to javafx.fxml;

    exports ru.viewer.expensesviewer.model.objects.settings;
    opens ru.viewer.expensesviewer.model.objects.settings to javafx.fxml;
}
