ASF GitHub Bot commented on AVRO-2268:
--------------------------------------

rstata opened a new pull request #382: AVRO-2268 Fix FooBarSpecificRecord case
URL: https://github.com/apache/avro/pull/382
 
 
   Array fields for specific records should be given `List<>` implementations that support the `List.clear` operation.  The class returned by `Arrays.asList` does not support `clear`, so use an `ArrayList` instead.

> In {{FooBarSpecificRecordTest.genSingleRecord}}, the {{nicknames}} field is given an instance of what is returned by {{ArrayList.asList}}, which does _not_ support the {{clear}} method.  When reusing objects during a read, the {{clear}} method is used to clear the contents of array-valued fields during reading, which causes an {{OperationNotSupported}} exception.  So {{genSingleRecord}} needs to change to set {{nicknames}} to a type that implements {{clear}}.
