I can confirm that this was the same error I was seeing when trying Java 11 using Struts 2.5.18. It is happening in the convention pluggin on the startup of the server when it scans for actions to configure Struts. It is not a compile issue, but happening at runtime.

But the compiler levels are specified as 11, yes. I do not know how to do it with maven. But it woul dbe relevant for the tests of the convention plugin to analyse some Struts2 action class with class version 55.
