you can simply replicate when cloning PrimeFaces:

• mvn clean install -DskipTests
• cd primefaces-integration-tests-jakarta
• mvn clean package jetty:run -Pmojarra-4.0

and the exception is thrown on startup

Could be the same as: https://github.com/eclipse-ee4j/mojarra/pull/5195

I´m able to confirm https://github.com/eclipse-ee4j/mojarra/pull/5195 fixes this issue. (I checked out this PR, built it and successful run primefaces-integration-tests-jakarta.)

Okay.
