每当我部署jetty应用程序时，我都遇到了这个问题。看起来像一些jar或类被打破。
git和maven）~/.m2并重建没有帮助。jar被打破。尝试jar tvf $every_jar并没有找到任何东西。任何想法如何调试这个？看起来真的很神秘，我怀疑是有些文件被破坏了。

对于你的2个错误..
javax.servlet.ServletException: jersey-serlvet
这意味着你的WEB-INF/web.xml有一个拼写错误
至于这一个......
java.lang.ArrayIndexOutOfBoundsException: 6241
at org.objectweb.asm.ClassReader.<init>(Unknown Source)
当我使用旧版本的asm.jar和更新的编译Java字节码时，我见过类似的东西。
确保你的asm.jar（或org.objectweb.asm.jar）是最新的。
课程本身很糟糕，这个问题稍微不那么常见。有时会看到在一个JDK（例如IBM）中编译的类，然后在另一个Java（如Sun / Oracle）上运行。
一个现实世界的例子是the icu4j-2.6.1.jar and its com/ibm/icu/impl/data/LocaleElements_zh__PINYIN.class jar entry。
使用更新版本的jetty-maven-plugin。

所以，像这样编辑你的pom.xml：
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.3.0.M2</version>
</plugin>
注意groupId是“org.eclipse.jetty”。
我在维护遗留代码时遇到了类似的问题。

我通过减少web.xml中的包扫描范围来修复它。例如，删除param-value标签中的package_with_too_many_classes修复了该问题。
<servlet>
<servlet-name>JerseyServlet</servlet-name>
<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>package_with_too_many_classes;package_with_approciate_number_of_classes;org.codehaus.jackson.jaxrs</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
就我而言，我使用的是ASM库版本，并且不支持java 8 lambda表达式，因此要么更改ASM库以支持java 8，要么更改代码。
在我的情况下，我使用java 8 lambda表达式进行迭代，我用for循环替换它
