Description

I got this for some very large training file.

         Computing event counts...  Exception in thread "main" java.lang.RuntimeException: name spans [27..29) person and [27..27) person are overlapped in file: null
        at opennlp.tools.namefind.NameSample.<init>(NameSample.java:79)

With this exception it is impossible to track the error if you have a large training file.

 

Exceptions about mismatching <START:> and <END> tags at least give a little bit of context. This patch adds the sentence parts to the exception, making it simple to grep the training file for the bad sentence.
