             Summary: CASImpl.reinit doesn't properly check magic number
                 Key: UIMA-3142
                 URL: https://issues.apache.org/jira/browse/UIMA-3142
             Project: UIMA
          Issue Type: Improvement
          Components: Core Java Framework
            Reporter: Richard Eckart de Castilho
            Priority: Minor


Binary CASes have a magic number at the beginning of the file/stream: "UIMA". Currently, this information is only used to check the byte order (first byte is checked for being U).

CASImpl should also check if the other bytes of the magic number are correct and if not, it should throw an exception.
