I will see if I can create a test to replicate the two messages, but my
initial attempt was not successful, something else to hunt down.đ
Don't think its a release blocker, rather an annoyance.

There is no change in error flow, the parser just reports an error and
returns. And maybe that's the issue, and your custom field isn't
parsed at this point - the only option I see is to let the parser
finish and then return the final result instead of breaking in the
middle.

I managed to trace the source of the duplicate message. Basically, the
new error message shortcuts to calling "input" on my action.
.....I have a hidden field to check to make sure the upload is from my
form, and then I have an interceptor that checks the value and if
invalid calls input on my action, to show an error message.
<s:form id="uploadFiles" action="myUpload" method="POST"
enctype="multipart/form-data">
<s:hidden name="ckeckme" />
<s:form
The interceptor (extends MethodFilterInterceptor) adds an error:
theAction.addError("error.permissions.deniedCheck");
and then returns "input"
The input is a chain in my case (as I use list as the screen default,
tiles). If I change the input to tiles I get one message.
<action name="myUpload!*" method="{1}" class="my.Upload">
<!-- input for security check -->
<result name="input" type="chain">myUpload</result>
<result name="list" type="tiles">.MyUpload</result>
</action>
These seems to be some difference in the error flow, as the max file
size logic calls my execute, whilst the zero file size check shortcuts
to input, and then gets picked up by the workflow and adds the extra
message. For me.
I will experiment with changing my input to tiles and see what happens.

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.
