Key: AVRO-790
URL: https://issues.apache.org/jira/browse/AVRO-790
Project: Avro
Issue Type: Bug
Components: java
Reporter: Scott Carey
Assignee: Scott Carey
Fix For: 1.5.1
GenericDatumReader can fail when reusing GenericRecord objects that contain
unions of 'bytes' and other types.
Enhanced unit tests in TestSchema.java uncovered this.
Errors are of the form:
{code}
java.lang.ClassCastException: org.apache.avro.generic.GenericData$Array cannot
be cast to java.nio.ByteBuffer
