             Summary: Classloader Differences When Copying Records Results in ClassCastException
                 Key: AVRO-1620
                 URL: https://issues.apache.org/jira/browse/AVRO-1620
             Project: Avro
          Issue Type: Bug
          Components: java
    Affects Versions: 1.7.7
            Reporter: Allan Shoup


Similar to the situation described in AVRO-1240, a parent classloader contains the avro classes and a separate classloader contains the avro specific record classes. When using the generated 
{code}
newBuilder(SpecificRecord other)
{code}
or 
{code}
newBuilder(SpecificRecord.Builder other)
{code}
methods to duplicate records, the generated code will cause an exception similar to this:
{noformat}
Caused by: java.lang.ClassCastException: org.apache.avro.generic.GenericData$Record cannot be cast to my.specific.Record
	at my.specific.Record$Builder.<init>(Record.java:149)
	at my.specific.Record$Builder.<init>(Record.java:121)
	at my.specific.Record.newBuilder(Record.java:115)
	... 19 more
{noformat}
