[coryfoo]

Environment details

1. Specify the API at the beginning of the title. For example, "BigQuery: ...").
   General, Core, and Other are also allowed as types
2. OS type and version: OSX / Linux
3. Java version: JDK 11
4. bigquery version(s): 1.111.0

Steps to reproduce

1. Initialize BigQuery service in project A
2. Call getDataset using a DatasetId consisting of another project (eg, project B) and a valid dataset in that project
3. Call get for a table ID of a table that exists in that project.
4. The get returns null, when it should return a Table object

Code example

final String projectA = "...";
final String projectB = "...";

final BigQuery instance = BigQueryOptions
        .newBuilder()
        .setProjectId(projectA)
        .build()
        .getService();

final String datasetName = "some_dataset";
final String tableName = "some_table";
final Dataset ds = instance.getDataset(DatasetId.of(projectB, some_dataset));
ds.get(tableName); // <--- this returns null, should not
