Subject [jira] [Commented] (CXF-3750) Sometimes, CXF servlet will blocked until bussiness logical finished for one-way operation
Date Mon, 22 Aug 2011 05:00:29 GMT

    [ https://issues.apache.org/jira/browse/CXF-3750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13088533#comment-13088533
] 

ext2 commented on CXF-3750:
---------------------------

the patch may cause a problem: when the user's business logic reached a runtime exception
in the one-way operation, a  temporary file of big attachment will be left on the disk;

The reason details is: 
1) one way interceptor will cache the input stream to avoid underly transport discard data
(patch of CXF-3750 did), this may create a temporary file in disk when the request contains
a big attachment;

2) if user's business logical has no exception, so when ServieInvokeInterceptor finished,
the OutgoingChainInterceptor will release input stream then temporary file will be released;
OutgoingChainInterceptor.handleMessage(){
    if (null != bin && null != bin.getOperationInfo() && bin.getOperationInfo().isOneWay())
{
            closeInput(message); //here , the temporary file will be released
            return;
        }
}

3) if user's business logical reached a runtime exception (unhandled) , ServieInvokeInterceptor
 return ABORT, so OutgoingChainInterceptor  will not executed continously, then the temporary
file will not be released
