Subject UIMA AS NullPointerException in CasDefinition constructor
Date Mon, 28 Jul 2014 15:46:58 GMT

I'm trying to convert an existing and functional UIMA pipeline to a UIMA AS pipeline.

I'm getting there, I created deployment descriptors for the annotators and when 
running my application all individual annotators are launched correctly. The composite 
analysis engine also loads fine but I'm getting a NullPointerException when calling 
initialize(deployCtx) on the UimaAsEngine on line 66. See the attached text document 
for the full exception.

I found a similar issue in the bug tracker which was fixed in UIMA AS 2.3:


But this seems to arise in mergeTypeSystem and this does not seem to be the case in 
my situation. The line number is the same however.

Any clues on where I should look for the solution? Are my descriptors faulty? Is the Java

code faulty? Or is this a bug in UIMA AS 2.4.0? How can I debug this issue?
