I am working with Eclipse 2021-09 (4.21.0) and later to install the Plugin JBoss Tools, I observed that when I want to open a .xhtml file, the Eclipse give me the following error.
Maybe any idea.

Reviewing the eclipse documentation, I can see the Bug 
- Change the configuration related to JBoss Tool Editor -> Visual Page Editor to open the .xhtml files with the source tab only.
I hope the post will be useful for us.
