Richard Eckart de Castilho updated UIMA-6162:
---------------------------------------------
Description:
I suspect there could be an issue in `BinaryCasSerDes`.
When deserializing the attached file `admin.ser`, I get this stack trace:
{code:java}
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.
The code used to read the file before deserializing is as follows:
{code:java}
public static void readSerializedCas(CAS aCas, File aFile)
throws IOException
{
try (ObjectInputStream is = new ObjectInputStream(new
FileInputStream(aFile))) {
CASCompleteSerializer serializer = (CASCompleteSerializer)
is.readObject();
deserializeCASComplete(serializer, (CASImpl) aCas);
}
catch (ClassNotFoundException e) {
throw new IOException(e);
}
}
{code}
