-------------------------------
Summary: PythonFunctionRunner doesn't extend AutoCloseable but
implements close
Key: FLINK-31281
URL: https://issues.apache.org/jira/browse/FLINK-31281
Project: Flink
Issue Type: Improvement
Reporter: Ran Tao
The PythonFunctionRunner provides a {{close}} method (see
[PythonFunctionRunner|https://github.com/apache/flink/blob/0612a997ddcc791ee54f500fbf1299ce04987679/flink-python/src/main/java/org/apache/flink/python/PythonFunctionRunner.java])
but doesn't implement {{{}AutoCloseable{}}}. However {{AutoCloseable}} would
enable us to use Java's try-with-resources feature and more generic utility
classes.
