Hi Peter,
You can find the eclipse project attached.
> Ruta and UIMA-AS
> ----------------

> Key: UIMA-3368
> URL: https://issues.apache.org/jira/browse/UIMA-3368
> Project: UIMA
> Issue Type: Bug
> Components: Async Scaleout, ruta
> Affects Versions: 2.4.0AS, 2.1.0ruta
> Reporter: Prokopis Prokopidis
> Priority: Minor
> Attachments: SimpleAnnotator.zip

> Hi,
> I get errors when applying Ruta rules from an Annotator deployed as a UIMA-AS
> service. Here's my situation.
> I have a SimpleAnnotator class that assigns tags to Tokens. So, when I have a
> test.txt in my input with this content:
> $ more test.txt
> A room .
> ... I get, among other things, the following output
> {code:xml}<examples:Token xmi:id="21" sofa="1" begin="1" end="2" pos="aTag"/>
> <examples:Token xmi:id="26" sofa="1" begin="3" end="7" pos="anotherTag"/>
> {code}
> To get the tags, I use java code as in the attached SimpleAnnotator.java and
> ruta rules.
> All's fine when I run this a standard UIMA pipeline. But, if I deploy the
> annotator in UIMA-AS and I send the same text to the queue created, I get
> NullPointerException's similar to those:
> Caused by: java.lang.NullPointerException
