@xkrogen Please do not involve corporate/enterprise thinking/talking into
OSS project unless your enterprise wants to offer its help!
Most of us do this in our spare time!
The best you could do is to test Avro master (1.11.0-SNAPSHOT) in your
application and give feedback! If you find more regressions then you will have
more ground to ask for 1.10.x!

> Key: AVRO-3048
> URL: https://issues.apache.org/jira/browse/AVRO-3048
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.9.2, 1.10.1
> Reporter: Peter
> Assignee: Martin Jubelgas
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.11.0
>
> Time Spent: 50m
> Remaining Estimate: 0h

> When you do a .newBuilder() for avro generated classes, this will call
> org.apache.avro.specific.SpecificData.getForSchema:
>
> public static SpecificData getForSchema(Schema reader) {
> if (reader.getType() == Type.RECORD) {
> final String className = getClassName(reader);
> if (className != null) {
> final Class<?> clazz;
> try
> {
> clazz = Class.forName(className);
> return getForClass(clazz); }
> catch (ClassNotFoundException e)
> { return SpecificData.get();
> }
> }
> }
>
> which seems then to seldom find the value inside the try and a lot of
> ClassNotFoundException is thrown.
> Throwing internal exceptions has great performance penalties and in practice
> users of avro 1.9.x. and 1.10.x in high performance applications are forced
> not to use builders.
>
> Information about same problem is also found on:
> [https://forums.databricks.com/questions/50803/orgapacheavrospecificspecificdatagetforschema-sear.html]
> Problem exists on at least 1.9.2 and 1.10.1 (but not on 1.7.x) in OSGI
> environment
