Upload File - Undertow

[marcosbarbero]

I'm trying to upload a file using Undertow and it's giving throwing me the following exception.
I don't know exactly what is going on, but if I change from Undertow to Tomcat it just works fine.

Anybody have the same issue?

What OS are you running on and what are you doing with the uploaded file? I would guess that you've opened an InputStream to read the uploaded file but haven't closed it. On some OSes (Windows, for example) that will cause File.delete() to fail.

[marcosbarbero]

Hi @wilkinsona I'm using Mac OS and CentOS.
Maybe I've opened the issue in the wrong project because the problem is happening on Zuul proxy (spring-cloud-netflix)

[marcosbarbero]

Just checked and the same behavior happens on pure spring-boot application using undertow.

[wilkinsona]

Thanks for the info. Sounds like the issue's in the right place. Can you share the code that you're using to trigger the problem please?

[marcosbarbero]

To reproduce the main problem I'm using this project from spring guide https://github.com/spring-guides/gs-uploading-files.git, I'm using the complete version with two approaches.

1. I change spring-boot to spring-cloud dependency and tomcat to undertow. After that I do access it from zuul endpoint.
2. I just exclude tomcat dependency and add undertow as webserver and run it as standalone application with spring-boot

[wilkinsona]

Thanks again. The good news is that the exception's benign and you can safely ignore it. All it's telling you, albeit very noisily, is that the file couldn't be deleted as it's already been deleted. The reason is that there's a race condition in Undertow that means that two threads end up trying to delete the file at the same time. I've opened UNDERTOW-542.

[marcosbarbero]

Thanks for the answer @wilkinsona! I just noticed that running with pure spring-boot application it works fine, otherwise, if I send this file through zuul proxy it isn't delivered to the final service endpoint.
Maybe a zuul issue? It works fine doing same thing using tomcat instead.

[wilkinsona]

This has been fixed in Undertow 1.3 and 1.2. Spring Boot 1.3 uses Undertow 1.3 so we're good there. Unfortunately Spring Boot 1.2 uses Undertow 1.1 so we'll just have to live with the benign warning there.

[marcosbarbero]

@wilkinsona Thanks for the info.
Sounds great to me.

[bmstefanski]

Is it fixed? I just got an error

@bmstefanski The problem tracked in this issue was actually in Undertow. We believe it was fixed. If you're seeing the same problem, or perhaps the same symptom from a different problem, I'd recommend reporting it to the Undertow team, ideally with a minimal sample that reproduces the problem.

Is it fixed? I just got an error
