------------------------------------------------
Summary: Sofa not found when deserializing CAS
Key: UIMA-6162
URL: https://issues.apache.org/jira/browse/UIMA-6162
Project: UIMA
Issue Type: Bug
Components: UIMA
Affects Versions: 3.1.1SDK
Reporter: Richard Eckart de Castilho
Attachments: admin.ser
I suspect there could be an issue in `BinaryCasSerDes`.
When deserializing the attached file `admin.ser`, I get this stack trace:
{noformat}
Caused by: java.lang.ClassCastException: class
org.apache.uima.jcas.tcas.Annotation cannot be cast to class
org.apache.uima.jcas.cas.Sofa (org.apache.uima.jcas.tcas.Annotation and
org.apache.uima.jcas.cas.Sofa are in unnamed module of loader

I set a breakpoint to BinaryCasSerDes:1608 which is a for loop iterating over
the heap. Apparently, the first feature structure that is encountered is an
annotation type which is NOT the sofa. Then in line 1700, the deserializer
tries to resolve the sofa for this annotation but fails because it has not yet
been deserialized.
