   Since CALCITE-3323 is fixed already, can you please create a new JIRA case. The description is "CalciteConnectionConfigImpl.set obliterates previous property values".
   
   The cause is that `new Properties(properties)` doesn't copy the previous value as, say, `new HashMap(map)` does.
   
   Can you add a unit test, say in PlannerTest, that if you call set(x, 1) then set(y, 2) on a CalciteConnectionConfigImpl, the result contains x and y.
