[jira] Commented: (CXF-2542) DelegatingInputStream.close() causes MessageImpl.getContextualProperty throw NullPointerException

["Daniel Kulp (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CXF-2542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12778418#action_12778418 ] 

Daniel Kulp commented on CXF-2542:
----------------------------------


Is there a stack trace for when this occurs in a "real life" scenario.   In theory, when this is called as part of the  AttachmentDeserializer stuff, the Exchange would always be set in the message.    Thus, the null check wouldn't be needed.     

I have no problem adding the null checks, but I'm curious as to why it really is needed in a normal case.   :-)

> Parsing AttachmentDeserializer's attachments causes an NPE in MessageImpl.getContextualProperty sometimes. This can be fixed by adding a null check in MessageImpl's getContextualProperty method.
> This problem exists in 2.2.4, it did not exist in 2.2.2. It was caused by a change in DelegatingInputStream's close behavior.
