Wolfgang Knauf commented on TOMEE-4418:
---------------------------------------
Not really, it is part of a rather complex testsuite, and it will require a bit
of work and research until the migration to TomEE 10 is available on github. If
you are willing to take a look, I can post guidelines to reproduce the issue
when it is committed.
Currently, I consider my initial request a "won't fix", as it does not seem to
be possible and I found an easy workaround.
> "arquillian-tomee-remote": SerialVersionUID conflict with ServletException
> --------------------------------------------------------------------------
>
> Key: TOMEE-4418
> URL: https://issues.apache.org/jira/browse/TOMEE-4418
> Project: TomEE
> Issue Type: Bug
> Components: TomEE Arquillian Adapters
> Affects Versions: 9.1.3, 10.0.0-M2
> Reporter: Wolfgang Knauf
> Priority: Minor
>
> When updating a project to JakartaEE and TomEE 9, I noticed this problem: the
> project has one unit test that triggers a ServletException on the server
> side, which is caught, serialized and deserialized on the client side.
> The client side is a unit test driven by "arquillian-tomee-remote".
> Unfortunately, the underlying Tomcat library
> ([https://repo.maven.apache.org/maven2/org/apache/tomcat/tomcat-servlet-api/10.0.27/tomcat-servlet-api-10.0.27.jar)]
> contains a ServletException with a SerialVersionID of "1", which is not the
> same as the version in the JakartaEE reference implementation.
> Now the problem: my test project has those dependencies:
>
> {quote}{{<dependency>}}
> {{ <groupId>org.apache.tomee</groupId>}}
> {{ <artifactId>arquillian-tomee-remote</artifactId>}}
> {{ <version>9.1.3</version>}}
> {{ <scope>test</scope>}}
> {{</dependency>}}
> {{<dependency>}}
> {{ <groupId>org.apache.tomcat</groupId>}}
> {{ <artifactId>tomcat-servlet-api</artifactId>}}
> {{ <scope>provided</scope>}}
> {{ <version>10.0.27</version>}}
> {{</dependency>}}
> {quote}
>
> With the previous version, this worked. But with the new arquillian adapter,
> it pulls in
> [https://repo.maven.apache.org/maven2/org/apache/tomee/jakartaee-api/9.1.1/jakartaee-api-9.1.1.jar]
> , which also contains a ServletException, but with a different
> SerialVersionUID.
> Thus, the test fails:
> {{class java.io.InvalidClassException: jakarta.servlet.ServletException;
> local class incompatible: stream classdesc serialVersionUID = 1, local class
> serialVersionUID = 4221302886851315160}}
>
> My workaround: exclude "org.apache.tomee:jakartaee-api" from the arquillian
> adapter, then add it back after declaring the Tomcat servlet api (the one
> with the "1" SerialVersionUID). It seems the ServletException is now loaded
> from the first jar, and my test works.
> {quote}{{<dependency>}}
> {{ <groupId>org.apache.tomee</groupId>}}
> {{ <artifactId>arquillian-tomee-remote</artifactId>}}
> {{ <version>9.1.3</version>}}

> {{ <exclusions>}}

> I have no idea whether this is anything that you could change. It would work
> if the arquillian adapter would pull the tomcat servlet api first. Or the
> Tomcat guys could fix the SerialVersionUID ;).
