Deadlock when echoing MTOM attachments back to client
-----------------------------------------------------
Key: CXF-2619
URL: https://issues.apache.org/jira/browse/CXF-2619
Project: CXF
Issue Type: Bug
Components: Core
Affects Versions: 2.2.5, 2.2.4, 2.2.3, 2.2.6
Environment: Windows XP
Reporter: aaron pieper
Priority: Minor
I've written a simple "echo" web service, which receives an attachment and
echoes it back. In CXF 2.2.2 and earlier, this works OK. Starting with CXF
2.2.3, however, there is a somewhat unpredictable deadlock situation which
occurs with MTOM attachments, which causes the web server to deadlock, so that
it never responds to the request.
This situation often occurs when the attachment is around 85 kilobytes or
greater in size. However, this boundary is not 100% consistent. Sometimes I can
successfully echo attachments up to 88 kilobytes in size, and sometimes smaller
attachments trigger the bug.
The behavior only occurs if the same input stream is reused. Copying the input
into a new input stream circumvents the error. I've verified this behavior
began with CXF 2.2.3, and is still present in the latest 2.2.6-SNAPSHOT.
