With the newest versions of the jboss wildfly being compatible to the Jakarte EE 10 specs we updated our JEE 8 projects. In this process we updated all our components, but afterwards the newest verion of eclipse had a bugged handling of our projects.
Most importantly the Deployments Descriptor was not handled correct and it was not possible to deploy our projects using the add and remove option of the application server.

After a while we found out, that the actual version of eclipse does not support the web.xml in the version 6.0 yet. (https://i.stack.imgur.com/ldQ4D.png)
Changing the web.xml to the version 5.0 made the projects running again.
