Oracle has responded to my service request. It appears that changes to
Log4j to support Java 9 break Weblogic's classloader. There is a new
bug for this issue: Bug 27098427 : JAVA.LANG.ILLEGALARGUMENTEXCEPTION
DEPLOYING APP ON WLS 12.1.3 WITH PSU
For now, it is possible to work around this issue by using Log4j 2.8.x.
I added a dependency for log4j-api and log4j-core, version 2.8.2. The
application appears to work fine, thought it does generate a spectacular
error message covered by this WW-4920, which is apparently addressed in
Struts 2.5.16.

12.1.3.0.160719
I tried downgrading the Weblogic PSU and that appears to work. One can
also downgrade the Struts version. Struts 2.5.12 works for me with the
latest Weblogic PSU. (27057030).

the app and running Weblogic.
I did some more experimenting. I tried removing CDI from my source
code and the Maven pom. I still get the error with a complete
stripped down application (the only dependency being Struts), so CDI
isn't at issue here.
The word from Oracle is that this problem appears to have been
introduced into WLS 12.1.3 between the July 2016 and January 2018
Critical Patch Updates (that is, Struts works with the earlier patch
and does not work with the latter). I, of course, am running with the
latest updates.
Thanks.
