runtime error when casting Array to String[]

[Weishung Chung]

Hello fellow Avro users,

Do you guys have this problem when casting Array<String> to String[]?
Am I missing something here :(

I got a runtime exception as follows

Exception in thread "main" java.lang.ArrayStoreException:
org.apache.avro.util.Utf8
at java.util.AbstractCollection.toArray(AbstractCollection.java:171)

Array<String> idsArray = (Array<String>) rec.get("ids");
String[] ids = (String[]) idsArray.toArray(new String[idsArray.size()]);

Thank you
