Why StandardSQLTypeName.ARRAY doesn't work?

[haikuo-google]

Environment details

I am using client version 2.6.1 from MVN: https://mvnrepository.com/artifact/com.google.cloud/google-cloud-bigquery/2.6.1

Steps to reproduce

Please simply run the code example below.

Code example

Field.newBuilder("abc", StandardSQLTypeName.ARRAY).build();

Stack trace

java.lang.NullPointerException
    at com.google.common.base.Preconditions.checkNotNull (Preconditions.java:878)

Any additional information below

It looks like the client is always trying to convert the Field type from StandardSQLTypeName to LegacySQLTypeName, but there isn't an ARRAY in LegacySQLTypeName, causing the type to be null, which shouldn't be. How do we specify ARRAY type then?

java-bigquery/google-cloud-bigquery/src/main/java/com/google/cloud/bigquery/Field.java

Line 189 in dfa15e5

public Builder setType(StandardSQLTypeName type, FieldList subFields) {

Never mind, I saw an old issue, I will try the suggested approach, but I think it would still be good to fail in a friendly way.
