L.S.,
No, any XML file should do. Could you try actually something beyond the
PI in your XML file? Something like <?xml version="1.0"
encoding="UTF-8"?><message>my message</message>
I suspect not having a root element at all gives problems when a parser
tries to read it.

Gert,
Thank you for your response. It's good to know the issue is being worked on.
After commenting the line in servicemix.xml, getting a different error.
Please see trace below. My test file is called file.xml and it has a single
line: <?xml version="1.0" encoding="UTF-8"?>. Do you know whether certain
file format is expected?

L.S.,
It looks like you have run into
https://issues.apache.org/activemq/browse/SM-1456. We should get that
issue fixed ASAP, but in the meanwhile you can work around this issue by
removing the <sm:statistics statsInterval="10" dumpStats="true" /> line
from conf/servicemix.xml (or commenting the line) to disable the
StatisticsService that is throwing this exception.

I have created a service-assembly example from the tutorial (at
http://servicemix.apache.org/25-beginner-deploying-the-service-assembly.html).
My service-assembly example deploys/runs fine when there is no file to
copy
from "sender" directory to "poller". When there is a file, the
service-assembly example is throwing a NullPointerException. Has anyone
seeing same/similar problem? This happens when test file gets copied from
"sender" directory to "poller". Please see details attached. Thank you.
