[GitHub] [beam] RustedBones opened a new issue, #28279: [Bug]: Concurrency issue when using addLogicalTypeConversions on avro model data

RustedBones opened a new issue, #28279:
URL: https://github.com/apache/beam/issues/28279

   ### What happened?
   
   Since beam `2.48` after #26320, we can see the following exception
   
   ```log
   "java.lang.NullPointerException
   	at org.apache.avro.generic.GenericData.addLogicalTypeConversion(GenericData.java:116)
   	at org.apache.beam.sdk.extensions.avro.schemas.utils.AvroUtils.addLogicalTypeConversions(AvroUtils.java:169)
   	at org.apache.beam.sdk.extensions.avro.io.AvroDatumFactory$ReflectDatumFactory.apply(AvroDatumFactory.java:188)
   	at org.apache.beam.sdk.extensions.avro.io.AvroIO$Sink.open(AvroIO.java:2126)
   	at org.apache.beam.sdk.extensions.smb.FileOperations$Writer.prepareWrite(FileOperations.java:219)
   	at org.apache.beam.sdk.extensions.smb.FileOperations$Writer.access$100(FileOperations.java:206)
   	at org.apache.beam.sdk.extensions.smb.FileOperations.createWriter(FileOperations.java:133)
   ```
   
   Either in the `AvroIO` or in the `AvroCoder`.
   This seems to happen due to a concurrency access on the same `GenericData` (During initialization of the datum reader and writer, there is a high chance for avro returning the singleton instance).
   
   The `ReflectDatumFactory` should avoid concurrent access to avro's model data.
