我使用了JETTY 10和JAVA 11。还添加了JSP模块及其依赖项。仍在运行码头时，我要低于错误。我已经使用了自定义classloader。

I have used jetty 10 and java 11. Also added jsp module and its dependencies. Still while running jetty i'm getting below error. I have used custom classLoader.

com.quickheal.loader.WebAppClassLoader.loadClass(WebAppClassLoader.java:26)

那是您问题的原因。

您的自定义classloader必须遵循Servlet规范的所有规则，它的WebApp隔离和Jetty的webappClassLoader webappContext

该图层从来没有一个普通的Java Classloader。

请注意，许多使用servlet的库也期望同一类负载器的行为（包括类似的诸如类缓存，权限，servlet约束之类的微妙事物，java.lang.instrument.instrument.classfiletrument.classfiletrytrysformer支持，系统与服务器隔离，倒置，倒置父母的优先级等）

com.quickheal.loader.WebAppClassLoader.loadClass(WebAppClassLoader.java:26)

That is the cause of your issues.

Your custom classloader has to follow all of the rules for both the Servlet Spec and it's WebApp isolation and Jetty's WebAppClassLoader expectations within WebAppContext

That layer is never a normal Java ClassLoader.

Be aware that many libraries that use Servlet also expect behaviors from the same ClassLoader (including subtle things like Class caching, permissions, servlet constraints, java.lang.instrument.ClassFileTransformer support, system vs server isolation, inverted parent priority, etc)
