gbloisi-openaire opened a new pull request, #42914:
URL: https://github.com/apache/spark/pull/42914
### What changes were proposed in this pull request?
This pull request adds Encoders.bean support for beans having a superclass
declared with generic type arguments.
For example:
```
class JavaBeanWithGenericsA<T> {
public T getPropertyA() {
return null;
}
public void setPropertyA(T a) {
}
}
class JavaBeanWithGenericBase extends JavaBeanWithGenericsA<String> {
}
Encoders.bean(JavaBeanWithGenericBase.class); // Exception
```
That feature had to be part of [PR
42327](https://github.com/apache/spark/commit/1f5d78b5952fcc6c7d36d3338a5594070e3a62dd)
but was missing as I was focusing on nested beans only (@hvanhovell )
### Why are the changes needed?
JavaTypeInference.encoderFor did not solve TypeVariable objects for
superclasses so when managing a case like in the example above an exception was
thrown.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Existing tests have been extended, new specific tests have been added
### Was this patch authored or co-authored using generative AI tooling?
No
@hvanhovell this is branch-3.4 port of
[PR-42634](https://github.com/apache/spark/pull/42634)
