> Key: CAMEL-3997
> URL: https://issues.apache.org/jira/browse/CAMEL-3997
> Project: Camel
> Issue Type: Bug
> Reporter: Ashwin Karpe
> Assignee: Willem Jiang
> Fix For: 2.7.3, 2.8.0
>
>
> There seems to be an issue related to tmp file created by CachedOutputStream.
>
> My issue:
> 1. send a SOAP request to CXF consumer with a attachment whose size is
> larger than 64K
> 2. In my bundle, I will get the attachment by following code:
>
> from("cxf:bean:foobarEndpoint")
> // foobarEndpoint is defined in bundle-context.xml
> // <cxf:cxfEndpoint id="foobarEndpoint"
> // serviceClass="com.mycompany.FooBar">
> // </cxf:cxfEndpoint>
> .doTry()
> .to("log:myInboundLogRoute -> Start")
> .process(retrieveAttachment())
> .doCatch(Exception.class)
> .doFinally()
> //.process(removeAttachment())
> .end()
> .to("log:myInboundLogRoute -> End");
>
>
> private Processor retrieveAttachment() {
> return new Processor() {
> public void process(Exchange exchange) throws Exception {
> if (LOGGER.isDebugEnabled())
> LOGGER.debug("retrieveAttachment start");
> // handle attachments
>
> java.util.Collection<org.apache.cxf.message.Attachment> atts =
> PhaseInterceptorChain
>
> .getCurrentMessage().getAttachments();
>
> if (LOGGER.isDebugEnabled()) {
> LOGGER.debug("retrieveAttachment done");
> }
> }
> };
> }
>
> 3. After the exchange is completed, there is a tmp file left under
> /tmp/cxf-tmp-***/ directory, which has the same size of attachment.
> Note:
> a. If the size of attachment < 64k, there will be no tmp file left.
> b. If in my bundle, I didn't invoke retrieveAttachment(), there will be
> no tmp file left.
>
> It seems that CachedOutputStream is not closed by CXF properly after the
> exchange is completed. I got some description from CachedOutputStream.java.
>
> 037 /**
> 038 * This output stream will store the content into a File if the stream
> context size is exceed the
> 039 * THRESHOLD which's default value is 64K. The temp file will store in
> the temp directory, you
> 040 * can configure it by setting the TEMP_DIR property. If you don't set
> the TEMP_DIR property,
> 041 * it will choose the directory which is set by the system property of
> "java.io.tmpdir".
> 042 * You can get a cached input stream of this stream. The temp file
> which is created with this
> 043 * output stream will be deleted when you close this output stream or
> the all cached
> 044 * fileInputStream is closed after the exchange is completed.

> This issues is happening both in both fuse4.2 and fuse4.3.
