-----------------------------------
Summary: NullPointerException in CasSerializerSupport when called
from JsonCasSerializer and features reference the cas:NULL element
Key: UIMA-4915
URL: https://issues.apache.org/jira/browse/UIMA-4915
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 2.8.1SDK, 2.7.0SDK
Environment: All
Reporter: Philip Parker
When serializing a CAS, if there are references to the NULL element (<cas:NULL
xmi:id="0"/>) in the features for an annotation, a NullPointerException is
thrown at line 693 of CasSerializerSupport. It appears that the
ll_getTypeForCode(0) returns null, resulting in a NullPointerException when the
"getName()" method is called on the return object.
The same CAS can successfully be serialized to XML using the XmlCasSerializer.
