It is not really a custom stack, it uses the workflow interceptor (to
call validate())
<interceptor-ref name="workflow">
<param
name="excludeMethods">execute,cancel*,previous</param>
</interceptor-ref>
There is something thing different to the logic used for the zero file
size check compared with the max file size check, where I don't get two
error messages. These should use the same logic.

I tested the empty file upload behaviour using the example app
https://github.com/apache/struts-examples/tree/main/file-upload
It uses single <s:actionerror/> tag and based on struts-default
package, and I get single error message:
File zero.txt for field upload is empty (0 bytes). Empty file uploads are not
allowed.
I assume you have used a custom interceptor stack (as you have
mentioned early) and that was the cause.
