William McNutt updated AVRO-4039:
---------------------------------
Description:
With a schema
{code:java}
{"type":"record","name":"Root","fields":[
{"name":"f_date_repeated","type":{"type":"array","items:
{"type":int",logicalType:"date"}}},
{"name":"f_time_repeated","type":{"type":"array","items":{"type":long",logicalType:"time-micros"}}},
{"name":"f_datetime_repeated","type":{"type":"array","items":{"type":string",logicalType:"datetime"}}}
]}
{code}
and converters added:
{code:java}
static{
GenericData.get().addLogicalTypeConversion(new Conversions.DecimalConversion());
GenericData.get().addLogicalTypeConversion(new
TimeConversions.DateConversion());
GenericData.get().addLogicalTypeConversion(new
TimeConversions.TimeMillisConversion());
GenericData.get().addLogicalTypeConversion(new
TimeConversions.TimeMicrosConversion());
GenericData.get().addLogicalTypeConversion(new
TimeConversions.TimestampMillisConversion());
GenericData.get().addLogicalTypeConversion(new
TimeConversions.TimestampMicrosConversion());
GenericData.get().addLogicalTypeConversion(new
TimeConversions.LocalTimestampMicrosConversion());
GenericData.get().addLogicalTypeConversion(new
TimeConversions.LocalTimestampMillisConversion());
}
{code}
we are get an exception (and similarly Instant cannot be cast to Long)
{code:java}

When the fields are instead an optional or required rather than an array, there
is no exception thrown.
