Maxim Solodovnik commented on WICKET-6535:
------------------------------------------
Actually {{servlet-api}} is being provided by any app server
for Tomcat it will be {{tomcat-servlet-api}}
Since this issue was reported against {{wicket-http2-tomcat}} module, I believe
it is OK to have {{tomcat-servlet-api}} in dependency tree as servlet-api (both
interface and implementation)
> Dependency conflict problems: Conflicting classes exist in different JARs

> Key: WICKET-6535
> URL: https://issues.apache.org/jira/browse/WICKET-6535
> Project: Wicket
> Issue Type: Bug
> Components: wicket-http2
> Affects Versions: 8.0.0-M8
> Reporter: PandaMonkey
> Priority: Major
>
> Hi, by analyzing the dependency tree of your pom.xml and source code, we
> found that several classes with the same name in different JARs, but they
> have different implementations. As the JVM only load the classes present
> first on the classpath and shadow the other duplicate ones with the same
> name. So the problem will lead to the "NoSuchMethodException" or
> "NoSuchMethodError". Please notice that. Hope this can help you.
