Benchao Li updated FLINK-33990:
-------------------------------
Description: TaskManager will create a new class loader for each flink job
even when it has no user jars, which may cause metaspace increasing. Flink can
use system classloader for the jobs without jars. A similar optimization has
been made in JM in FLINK-32265, it make sense to optimize it in TM. (was:
