Fokko opened a new issue, #3086: URL: https://github.com/apache/parquet-java/issues/3086
### Describe the bug, including details regarding any error messages, version, and platform. Discovered by plugging in RC1 into Spark: https://github.com/apache/spark/pull/48970 Failing test: https://github.com/Fokko/spark/actions/runs/12027509812/job/33528737000 ``` ... Cause: java.lang.RuntimeException: shaded.parquet.com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class org.apache.parquet.schema.LogicalTypeAnnotation$StringLogicalTypeAnnotation and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: org.apache.parquet.hadoop.metadata.ParquetMetadata["fileMetaData"]->org.apache.parquet.hadoop.metadata.FileMetaData["schema"]->org.apache.parquet.schema.MessageType["fields"]->java.util.ArrayList[1]->org.apache.parquet.schema.PrimitiveType["logicalTypeAnnotation"]) at org.apache.parquet.hadoop.metadata.ParquetMetadata.toJSON(ParquetMetadata.java:73) at org.apache.parquet.hadoop.metadata.ParquetMetadata.toPrettyJSON(ParquetMetadata.java:49) at org.apache.parquet.format.converter.ParquetMetadataConverter.readParquetMetadata(ParquetMetadataConverter.java:1594) ... ``` I checked the affected classes, and they haven't changed for a long time, so I believe it is the upgrade to the later version of Jackson. Spark uses the same version of Jackson, so I fixed it by allowing to serialize to `null`. Converting to JSON is used for debugging purposes: https://github.com/apache/parquet-java/blob/7644e27717e09d570d99f76cf5bb631122d374bf/parquet-hadoop/src/main/java/org/apache/parquet/format/converter/ParquetMetadataConverter.java#L1594 ### Component(s) _No response_ -- This is an automated message from the Apache Git Service.
