 Description   

This issue arise when the group data is set incorrectly by users. Sometimes users leave the group tags empty(mainly the group count) with no value.

Below is the case where the test fail with NullPointerException. The exception is not caught in AbstractIOHandler.java and is never sent to client app causing the error to be ignored.

We should catch the exception and send reject to clients.

  1. @testcase 14i
  2. @Receive a message with repeating groups in which the "count" field value for a repeating group is incorrect.

Can you attach the test case so that the field delimeters are not lost? Thanks.

I'm curious what's causing the NullPointerException, but this is not exactly a case of an incorrect NumInGroup value. A missing group count tag might appear similar, but it has significantly different implications. Without a group count tag, the repeating groups effectively do not exist from a parsing perspective.

When I modify test 14i to remove the group count field, I receive a reject saying "Tag not defined for this message type:336". This is what I would expect since tag 336 would appear to be included in the main message body (which would be invalid). I saw no NullPointerException. Was this possibly coming from your application code?
