Claus Ibsen commented on CAMEL-16197:
-------------------------------------
Can you test with Camel 3.7.2 which is the latest release and see if you can
reproduce anything there.
Camel 2.x is not active developed anymore, and we only fix criticial bugs or
CVEs
> CXF Attachment stay in file system after processing

> Key: CAMEL-16197
> URL: https://issues.apache.org/jira/browse/CAMEL-16197
> Project: Camel
> Issue Type: Bug
> Components: camel-cxf
> Affects Versions: 2.25.3
> Reporter: Manuel Shenavai
> Priority: Minor
> Attachments: attachments.zip
>
>
> Hi everyone,
>
> we are using the camel CXF component and found that the cleanup of cached
> attachments is not working as expected. CXF will persist attachments to disk
> whenever they exceed a certain limit in size: [cxf
> source|https://github.com/apache/cxf/blob/3.2.x-fixes/core/src/main/java/org/apache/cxf/io/CachedOutputStream.java#L433]
> If the attachments are consumed within the route, i.e. when they are used to
> send a message, the files will be removed from the filesystem. In case they
> are not used at all, the files will stay in the filesystem. So the CXF
> component somehow assumes that the attachments are consumed within the route.
>
> Example
> We send a message that contains a attachment to a CXF endpoint. The
> attachment-size exceeds the size threshold and therefore will be persisted to
> disk. During message processing the attachment will not be used (the endpoint
> is oneway and attachments are not used within the route). After message
> processing, the file stays in the filesystem.
>
> Reproduce with attached example project:
> # Start the Server.java test (starts the server taking the requests)
> # Start the Client.java (sends a request to the server)
> # Check the temp folder (printed in console by Client.java, in my case
> “C:\Users\me\AppData\Local\Temp\cxf-tmp-3330821712753099698)
> # Repeat executing Client.java and find for each run a new tmp-file
>
> Due to this file leaks, the filesystem will be filled up over time.
> Best regards,
> Manuel
