Problems with Struts2 Bootstrap 5.0.4

I am seeing errors in several Roller 6.1.4 pages including weblog edit =
and related to Struts2 Bootstrap. These errors prevent correct rendering =
of the pages.

We recently upgraded the Struts2 Bootstrap dependency to 5.0.4, but =
apparently 4.0.1 was the last version that supported Struts 2.5.x. I =
downgraded to 4.0.1 and these errors disappeared.

Maybe I've got something wrong in my local env, but I think we may need =
a quick 6.1.5 release.
