New issue 2500 by [email protected]: B2buaHelper.createRequest()
throws a NullPointerException if the request contains an empty header
http://code.google.com/p/mobicents/issues/detail?id=2500
What steps will reproduce the problem?
1. Forward a call through a B2BUA application.
2. Have the UA on one leg send a reinvite which contains an empty header
(for example, "Supported: ").
3. Call B2buaHelper.createRequest() to copy the re-invite for forwarding to
the other leg.
What is the expected output? What do you see instead?
Expected the re-invite to be forwarded to the other call leg. Instead, a
NullPointerException was thrown:
