Hi，Community： I add 4 complicated sqls in one job, and the job looks running well. But when I try to add 5th sql，the job failed at the beginning。 And throws errors info below： java.lang.RuntimeException: Could not instantiate generated class 'StreamExecCalc$23166' at org.apache.flink.table.runtime.generated.GeneratedClass.newInstance(GeneratedClass.java:67) at org.apache.flink.table.runtime.operators.CodeGenOperatorFactory.createStreamOperator(CodeGenOperatorFactory.java:47) at org.apache.flink.streaming.runtime.tasks.OperatorChain.createChainedOperator(OperatorChain.java:428) at org.apache.flink.streaming.runtime.tasks.OperatorChain.createOutputCollector(OperatorChain.java:354) at org.apache.flink.streaming.runtime.tasks.OperatorChain.createChainedOperator(OperatorChain.java:418) at org.apache.flink.streaming.runtime.tasks.OperatorChain.createOutputCollector(OperatorChain.java:354) at org.apache.flink.streaming.runtime.tasks.OperatorChain.<init>(OperatorChain.java:144) at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:373) at org.apache.flink.runtime.taskmanager.Task.doRun(Task.java:705) at org.apache.flink.runtime.taskmanager.Task.run(Task.java:530) at java.lang.Thread.run(Thread.java:748) Caused by: org.apache.flink.api.common.InvalidProgramException: Table program cannot be compiled.

As the warning shows OOM，Then I try to set -yjm -ytm to a big value(1024 -> 4096)，but this does not help. Thanks for your reply.
