Hi all,
We are building a web service using directly the RutaEngine, in the
inicialization the engine is built as:
UIMAFramework.produceAnalysisEngine(AnalysisEngineFactory
.createEngineDescription(createEngineDescription(RutaEngine.class,
RutaEngine.PARAM_RULES,
rule.getRule().getConditions()))));
And then we call method *process *passing the *JCas*.
All is ok but when we receive concurrent requests, starts to appears many
exceptions like these:
Caused by: java.lang.IllegalArgumentException: Document is ambiguous, use
one of the following instead : uima.tcas.DocumentAnnotation
de.tudarmstadt.ukp.dkpro.core.api.segmentation.type.Document
at
org.apache.uima.ruta.RutaEnvironment.getType(RutaEnvironment.java:459)
~[ruta-core-2.6.0.jar:2.6.0]
Caused by: java.lang.NullPointerException: null
at java.util.ArrayList.addAll(ArrayList.java:577) ~[na:1.8.0_66]
at
org.apache.uima.ruta.condition.ImplicitCondition.eval(ImplicitCondition.java:70)
~[ruta-core-2.6.0.jar:2.6.0]
Is UIMA Ruta thread safe? we are doing something wrong?
Thanks in advance,
JM
