我之前使用的是 Oracle JDK，但为了避免许可证问题，我迁移到了 OpenJDK。我选择了 Windows AdoptOpenJdk 8_192，但在 Eclipse 中使用 Tomcat 8.5 运行它时遇到了一些问题（这种情况仅在使用 Tomcat 运行时才会发生，桌面 Java 应用程序可以正常运行）。
Tomcat控制台输出如下：

我想知道如何解决这个问题。提前谢谢。

这并不是我的问题的正确答案，但它解决了问题：之前我使用的是 AdoptOpenJDK 的 OpenJDK 和 OpenJ9 JVM，所以我改用了 Hotspot 版本并且它起作用了。
Tomcat 8 和 OpenJ9 JVM 之间可能存在一些不兼容性。
