> Since FLINK-36336, {{JavaProgramTestBase#testJobWithObjectReuse}} enables 
> object reuse on the {{TestStreamEnvironment}} from {{MiniClusterExtension}}, 
> but test programs call 
> {{StreamExecutionEnvironment.getExecutionEnvironment()}}, which builds a new 
> environment from the context factory without that setting. So both variants 
> run without object reuse, in {{JavaProgramTestBaseJUnit4}} as well. On top of 
> that, {{HadoopIOFormatsITCase.testJobWithObjectReuse}} has called 
> {{super.testJobWithoutObjectReuse()}} since FLINK-29050.
> We should register the configured environment as context in both test bases, 
> let {{TestStreamEnvironment#setAsContext()}} carry object reuse over to the 
> environments it creates, and fix the {{HadoopIOFormatsITCase}} override.
