ok. I built the class files for the java files attached herein, add them to lucene-core-3.6.2.jar at org.apache.lucene.analysis and lucene-analyzers-3.6.2.jar at org.apache.lucene.analysis. I then added the path of the dependencies to classpath in the init.py file. I ran the typical index file using this customized analyzer through PythonAnalyzer and got the above error. Meanwhile, I had earlier ran the index file using standard analyzer before adding the classes and it worked. After running the index file with the customized analyzer failed, I tried again with the standard analyzer which had earlier worked before adding the classes but failed this time around with same error message as above. I guess the problem has to do with array compatibility in java and python but I don't really know. Thanks.
