When working on a change for Apache Polaris, I hit an error of the following form: ``` java.lang.NullPointerException at java.base/java.util.Objects.requireNonNull(Objects.java:233) at java.base/java.util.ImmutableCollections$MapN.containsKey(ImmutableCollections.java:1207) at org.apache.iceberg.rest.requests.CreateNamespaceRequest$Builder.setProperties(CreateNamespaceRequest.java:85) at org.apache.iceberg.rest.RESTSessionCatalog.createNamespace(RESTSessionCatalog.java:626) at org.apache.iceberg.catalog.BaseSessionCatalog$AsCatalog.createNamespace(BaseSessionCatalog.java:128) at org.apache.iceberg.rest.RESTCatalog.createNamespace(RESTCatalog.java:223) at org.apache.polaris.service.it.test.PolarisRestCatalogIntegrationTest.testCreateNamespaceWithReservedProperty(PolarisRestCatalogIntegrationTest.java:1376) at java.base/java.lang.reflect.Method.invoke(Method.java:580) at java.base/java.util.ArrayList.forEach(ArrayList.java:1596) at java.base/java.util.ArrayList.forEach(ArrayList.java:1596) ``` Looking closer, I see that in `java.util.ImmutableCollections.MapN`, the `containsKey` method looks like: ``` @Override public boolean containsKey(Object o) { Objects.requireNonNull(o); return size > 0 && probe(o) >= 0; } ``` This suggests to me that `containsKey(null)` should probably be avoided; to keep the same semantics I suggest that we can use `keySet().contains(null)`. -- This is an automated message from the Apache Git Service.
