RowTypeInfo hashcode change cause Flink Table API not working properly Starting From 1.6

Hi, all

Found a fatal bug starting from Flink 1.6, which cause Flink Table API can
not correctly extract table schema .

Jira
https://issues.apache.org/jira/projects/FLINK/issues/FLINK-13603?filter=allopenissues


 there is a change on Flink-core -> RowTypeInfo -> hashcode ,  this change
make FlinkTypeFactory recognize schema with same type but different field
name as a same TypeInfo ,  this cause table schema can not be parsed
correctly .

Is any plan to fix this ? as the reverting hashcode change may fix
the problem, but I'm not sure other side affect of this change .

Thanks
Jacky Du
