// Flink 2.2 API changes addressed in this module's source overrides:
// - CheckpointingMode moved (Flink 2.2): org.apache.flink.streaming.api.CheckpointingMode
//   is now @Deprecated; canonical path is org.apache.flink.core.execution.CheckpointingMode.
//   FlinkExecutionEnvironments.java, DoFnOperator.java, and FlinkPipelineOptionsTest.java
//   are overridden here to use the non-deprecated import.
//
// Flink 2.2 breaking changes that are SQL/cluster-layer only (no runner code change needed):
// - TLS cipher suite default changed (FLINK-39022): JDK 11.0.30+/17.0.18+/21.0.10+/24+
//   disabled TLS_RSA_* ciphers; new default uses ECDHE suites. Verify cipher support
//   on TLS-enabled clusters before upgrading.
// - StreamingMultiJoinOperator state format change (FLINK-38209): savepoints from Flink 2.1
//   with table.optimizer.multi-join.enabled=true are NOT compatible with 2.2.
// - SQL row NOT NULL now enforced (FLINK-38181): use table.legacy-nested-row-nullability
//   to restore prior (silent-ignore) behavior if needed.
