> Classloading Race condition with LogicalTypes.register
> ------------------------------------------------------
>
> Key: AVRO-2947
> URL: https://issues.apache.org/jira/browse/AVRO-2947
> Project: Apache Avro
> Issue Type: Bug
> Components: java, logical types
> Affects Versions: 1.10.0, 1.9.2
> Reporter: Michael Nielson
> Priority: Major
> Fix For: 1.11.0
>
>
> In the Java api you must register any custom logical types before you use
> them with:
> {{ LogicalTypes.register }}
>
> This must be done before the schema is parsed or the parsing process will not
> discover the logical type, additionally for generated classes the schema is
> parsed when the class is loaded.
> This creates a race condition where you must have your calls to register
> logical types happen before anything attempts to load your class.
>
> This could be a solution to the problem:
