I did some further research on this issue. Note: I am using CXF
3.0.0-milestone1.
In milestone1 release, LoggingInInterceptor checks for a
DelegatingInputStream; see below.
But using similar logic in my interceptor also leads to the "Stream closed"
error.
It appears in my configuration, the DelegatingInputStream
is not markable (ie, markSupported() returns false), so the
InputStream.reset() option is not available.
I also tried calling DelegatingInputStream.cacheInput(), to see if caching
the input would
circumvent the "Stream closed" error. That did not help.
Lastly, I do have an input-validation-interceptor that runs during the
INVOKE phase, I believe;
commenting out that validation-interceptor in the application-context
configuration had no effect.
Why is the input stream on the Message not being kept open after I reset it
(ie, call Message.setContent) ?
Thanks!
