Table proram cannot be compiled

Asahi Lee
你好!      我在使用flink 1.12.0版本的org.apach.flink.table.runtime.generated.CompileUtils.compile()方法,编译的DataSteam程序时,执行报错,提示:Table program cannot be compiled. This is a bug. Please file an issue.我发现最终的错误是 public abstract java.lang.Object org.apache.flink.api.java.functions.KeySelector.getKey(java.lang.Object) 没有实现,我使用的是泛型方式的实现;是编译程序不支持泛型吗?请问动态编译是否还有其他的解决方案?谢谢!
