I am using Java 1.8.0_131-b11 on Windows 7, 64-bit for both building 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.

Ah, right :) We have moved this dependency directly under the
Convention Plugin, so if you do not use it, there be no ASM jar.

What version of Java do you use to compile the project and what
version is used to run the Weblogic?

2018-01-19 20:05 GMT+01:00 <fullmit...@lycos.com>: Interesting. I looked at the dependencies included with the struts2-core Maven artifact and it appears that ASM 5.2 is not there. Is this on purpose? I see ASM is included in the lib file of the downloadable distribution and in the WEB-INF/lib directory of the sample applications. Needless to say,
since it isn't in the Maven dependency chain, it does not appear in my
application.
I tried adding ASM 5.2 to my pom, added some instructions to try to get
Weblogic to prefer the packages in the web application over Weblogic's own (don't know why that isn't the default behavior *shrug*) and got the same
failure.
I tried deploying the same application to Tomcat 9 and it worked fine, so it looks like either I'm configuring something wrong in Weblogic or Weblogic has a problem. I've opened a support request with Oracle to see what they
think.
Thanks!

It's probably because we have switched to the latest ASM 5.2 version
[1] but looks like Weblogic uses (repackaged one -
"com.bea.objectweb.asm") an old version of ASM. I think you should
request Oracle support for a solution, maybe they have a patch for the
Weblogic or try to downgrade version used in Struts.
