通过 JLink 创建的 JRE 缺少一些安全证书 (cacerts)

Question

我使用 JLink 工具创建了一个缩小的 JRE

jlink --add-modules java.base,jdk.crypto.ec --output jre

我创建了一个非常基本的应用程序，它连接到 https://www.example.com

当我使用 JDK 运行此应用程序时，一切正常。当我使用缩小的 JRE 运行它时，我得到以下信息：

我注意到lib\security\cacertsJDK 中的文件比缩小的 JRE 中的文件大得多（246KB vs 156KB）。当我将此文件复制到缩小的 JRE 中时，我的应用程序可以正常工作。

这表明 JLink 进程出于某种原因正在删除某些证书。我在文档或在线看不到任何解释。我错过了什么吗？

这是 Corretto 中的一个已知错误。
