[GitHub] [iceberg] Kontinuation commented on issue #5974: Spark: Query fails with `java.lang.UnsupportedOperationException` when using Kryo serialization

Kontinuation commented on issue #5974:
URL: https://github.com/apache/iceberg/issues/5974#issuecomment-1277087495

   The fix is fairly easy:
   
   ```diff
   diff --git a/core/src/main/java/org/apache/iceberg/SerializableTable.java b/core/src/main/java/org/apache/iceberg/SerializableTable.javaindex 8f8f27a76..a1e2ef7eb 100644
   --- a/core/src/main/java/org/apache/iceberg/SerializableTable.java+++ b/core/src/main/java/org/apache/iceberg/SerializableTable.java@@ -82,7 +82,7 @@ public class SerializableTable implements Table, Serializable {
        this.io = fileIO(table);     this.encryption = table.encryption();     this.locationProvider = table.locationProvider();
   -    this.refs = table.refs();
   +    this.refs = SerializableMap.copyOf(table.refs());
      }
    
      /**
   ```
   
   I wonder if we could add a parameterized test case with kryo serializer enabled to the smoke test, so that we can catch similar problems in CI.
