----------------------------

([https://github.com/confluentinc/schema-registry/issues/1677)]

> If you generate Java classes from schema, {{SCHEMA$}} variable differs from 
> the original schema. It causes issues like 
> [this|https://github.com/confluentinc/schema-registry/issues/868] and 
> [this|https://github.com/confluentinc/schema-registry/issues/1352] when using 
> Schema registry.
> The issue happens when the schema in the registry is configured externally 
> and then you try to use generated Java class. The schema in the registry does 
> not match the schema in the class and thus the write is refused.
> Technically it's easy to fix (see the attached patch) but I guess there will 
> be some backward compatibility concerns. 
> If it is not acceptable, would it be at least possible to add the 
> {{originalSchema}} context variable so we could solve it using custom 
> template.
> The patch is not final, its purpose is just to convey the idea.
