> Every generated Object.newBuilder() has downstream call to SpecificData.getForClass() since version 1.9.X which is ~37 times slower than version 1.8.2.
> This is due to the NoSuchFieldException thrown on every Builder instantiation.
> Sample code to run the benchmarks can be found [here|https://github.com/baruchshushi/avro-performance-degradation] 
> *JMH results for 1.8.2:*
> Result "com.example.Main.benchmark":
>  24.877 ±(99.9%) 0.153 ms/op [Average]
>  (min, avg, max) = (24.426, 24.877, 25.542), stdev = 0.272
>  CI (99.9%): [24.724, 25.030] (assumes normal distribution)
