I currently have a JSF application running on Wildfly 32.0.1 with Java 21, Mojarra 4.0.7 and Omnifaces 4.4.1.
Some of the pages allow the user to upload a file.
As long as there are no input validation errors, everything works as it should. The problem occurs when the user forgets to enter a required value and the input file has already been uploaded. In this case, the following exception is thrown:
11:20:58,866 ERROR [io.undertow.request] (default task-9) UT005023: Exception handling request to /mywebapp/test/attachmentTest.xhtml: jakarta.servlet.ServletException: java.lang.InstantiationException: io.undertow.servlet.spec.PartImpl

I already tried using the o:inputFile from Omnifaces, but the behaviour is the same.
Page Bean
package com.test;
import java.io.Serializable;
import jakarta.faces.view.ViewScoped;
import jakarta.inject.Named;
import jakarta.servlet.http.Part;
@Named
@ViewScoped
public class AttachmentTest implements Serializable
{
private static final long serialVersionUID = 1L;
private String description;
private Part uploadedFile;
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public Part getUploadedFile() {
return uploadedFile;
}
public void setUploadedFile(Part uploadedFile) {
this.uploadedFile = uploadedFile;
}
public String doSomething() {
// do something with uploaded file;
return "attachmentTest";
}
}

Scenario
- User uploads file on form and does not enter description (required input)
- Form validation fails because a required value was not set
- User enters description
- User uploads file
- User submits form
- Exception is thrown
Is there a way around this problem?
Is this a bug or am I missing something here?
Any help would be greatly appreciated!
Thank you!
