spuru9 opened a new pull request, #29692:
URL: https://github.com/apache/flink/pull/29692
## What is the purpose of the change
release-1.20 no longer compiles with Java 8 since 770a086545b (the backport
of #29630), so every build on the branch fails in `compile_ci`, e.g. branch
builds 80738 and 80741:
```
PythonTypeUtils.java:[1414,45] incompatible types: java.lang.Object[] cannot
be converted to PythonTypeUtils.DataConverter[]
```
Through the raw `TupleTypeInfo` cast, javac 8 infers the result of
`toArray(DataConverter[]::new)` as `Object[]`; javac 11+ (master, release-2.x)
does not.
## Brief change log
- Cast to `TupleTypeInfo<?>` instead of the raw `TupleTypeInfo` in
`PythonTypeUtils.TypeInfoToDataConverter#typeInfoDataConverter`.
## Verifying this change
Compiled `flink-python` with JDK 8 (1.8.0_504): fails without the change,
compiles with it, and `PythonTypeUtilsTest` passes.
