Hi again,
I was able to reproduce the problem also with the DaveDetector now. I wrote
a short unit test that I can provide upon request to demonstrate the problem.

Hi,
I currently encountered a problem with the XMI deserialization of a
feature structure after calling a remote C++ AS annotator from a CPE.
The szenario is the following:
1. I add a custom feature structure "DocumentData" containing an String
Feature (the document URL) to the CAS in my CPE. The exact URL causing
the problem is:
documentURL="http://www.gesundheitsnachrichten.net/live/navigation/live.php?navigation_id=11&_psmand=1";
2. The CAS get's serialized to XMI before sending it to a remote C++
TAE. I added a breakpoint to UimaSerializer.serializeCasToXmi() and get
the following part in the XMI string:
documentURL="http://www.gesundheitsnachrichten.net/live/navigation/live.php?navigation_id=11&_psmand=1";
So here the "&" character seems to be excaped correctly.
3. When the document comes back, the same feature in the XMI string
received in UimaSerializer.deserializeCasFromXmi() reads:
documentURL="http://www.gesundheitsnachrichten.net/live/navigation/live.php?navigation_id=11&_psmand=1";
an now the SAXParser throws the following exception:
org.xml.sax.SAXParseException: The reference to entity "_psmand" must
end with the ';' delimiter.
at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source)
at
org.apache.uima.aae.UimaSerializer.deserializeCasFromXmi(UimaSerializer.java:170)
at ...
because the "&" comes back unescaped. I'm sure the C++ annotator in
question doesn't change the feature in question and it also correctly
adds its own annotations. I suspect there's something wrong in
deserializing/serializing the CAS from XMI and back on the C++ side of
things.
Do you have any idea what might cause this problem or any suggestion
where I can start to further narrow down the problem?
The remote C++ AE is running with version "uimacpp-2.2.2-incubating".
