AVRO-3597: Allow custom readers to override string creation (#1847)
* AVRO-3597: recall method newInstanceFromString for backward compatibility
* AVRO-3597: add licence
> Recent changes in GenericDatumReader.java break compatibility

> Key: AVRO-3597
> URL: https://issues.apache.org/jira/browse/AVRO-3597
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.11.1
> Reporter: Viktor Dvoretskii
> Assignee: Christophe Le Saec
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m

> We use a custom SpecificDatumReader which overrides the string creation
> logic. It looks like this:
> {code:java}
> class CustomSpecificDatumReader<T> extends SpecificDatumReader<T> {
> @Override
> protected Object newInstanceFromString(Class c, String s) {
> // custom logic
> }
> } {code}
> With [this
> commit|https://github.com/apache/avro/commit/820ed6e5ea4417b5735078bfd26c99f1305ea363],
> the newInstanceFromString() method is no longer called. Instead, strings are
> created with the hard-coded logic within GenericDatumReader.ReaderCache.
> It would be appreciated if you made it possible to override the string
> creation logic used by GenericDatumReader.ReaderCache. Preferably make use of
> the newInstanceFromString() method again to maintain backward compatibility.
