It seems like you may need to include this dependency:
似乎您可能需要包含此依赖项：
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>rt</artifactId>
<version>2.2.10</version>
</dependency>
Or (haven't checked it yet but should work) you may need to change the scope to import for POM dependency.
或者（尚未检查但应该可以工作）您可能需要更改要导入 POM 依赖项的范围。
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>jaxws-rt</artifactId>
<version>2.2.10</version>
<type>pom</type>
<scope>import</scope>
</dependency>

The first part of the answer by @reta works for me. These are the relevant dependencies from my pom (Java 10):
@reta 回答的第一部分对我有用。这些是来自我的 pom (Java 10) 的相关依赖项：
<dependency>
<groupId>javax.xml.ws</groupId>
<artifactId>jaxws-api</artifactId>
<version>2.3.1</version>
</dependency>
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>rt</artifactId>
<version>2.3.1</version>
</dependency>

which is available in jdk-8, I wonder if you can use jdk-8 if possible might solve the issue.
在 jdk-8 中可用，我想知道如果可能的话，您是否可以使用 jdk-8 可能会解决问题。

I've got the same problem upgrading to Java 11 from Java 8.
我在从 Java 8 升级到 Java 11 时遇到了同样的问题。
The problem was change of behavior in ForkJoinPool, which classloader is as of jdk9 system classloader, not the main thread classloader, it can produce ClassNotFound exeptions hard to solve.
问题是ForkJoinPool 中的行为改变，该类加载器是 jdk9 系统类加载器，而不是主线程类加载器，它会产生难以解决的 ClassNotFound 异常。
