Initialization of annotator class "org.apache.ctakes.dictionary.lookup2.ae.DefaultJCasTermAnnotator" failed

[Leander Melms <Me...@students.uni-marburg.de>]

Hi,

I've been trying for hours to debug the error Initialization of annotator class "org.apache.ctakes.dictionary.lookup2.ae.DefaultJCasTermAnnotator" failed (The full output is attached below).

I'm running cTAKES 3.2.3 using Java8. With the help and efforts of the community (Joyce and Sean M.), I was able to update the Spring framework to get cTAKES running with Java 8. I've installed YTEX too. 

I'm trying to run the umls fast lookup from the command line - specifically with as a rest server (https://github.com/dirkweissenborn/ctakes-server <https://github.com/dirkweissenborn/ctakes-server>). I believe the error has nothing todo with the github repo, nor with the packaging using Java 8.

The AggregatePlainText AE works great; the only issue is that it can't find org.apache.ctakes.dictionary.lookup2.ae.DefaultJCasTermAnnotator for some reason. All resources are present. There is no extra space in <implementationName>org.apache.ctakes.dictionary.lookup2.concept.UmlsJdbcConceptFactory</implementationName>. 

I'm really stuck here and I have no idea, how I can investigate further / debug this. Any help is greatly appreciated.

Leander
