Xintong Song updated FLINK-35148:
---------------------------------
Issue Type: Technical Debt (was: Improvement)
> Improve InstantiationUtil for checking nullary public constructor
> -----------------------------------------------------------------
>
> Key: FLINK-35148
> URL: https://issues.apache.org/jira/browse/FLINK-35148
> Project: Flink
> Issue Type: Technical Debt
> Components: API / Core
> Reporter: Mingliang Liu
> Assignee: Mingliang Liu
> Priority: Minor
> Labels: pull-request-available
> Fix For: 1.20.0
>
>
> {{InstantiationUtil#hasPublicNullaryConstructor}} checks whether the given
> class has a public nullary constructor. The implementation can be improved a
> bit: the `Modifier#isPublic` check within the for-loop can be skipped as the
> {{Class#getConstructors()}} only returns public constructors.
> We can also add a negative unit test for this.
