ConverterMap.containsValue(null) returns false using coherence version 12.1.2 whereas it returns true on version 3.5.3.x, encountered an issue with oracle coherence version. Customer saw this behavior when 3.5.3.x cluster upgraded to version.
The Map class returned from the method is$ConverterMap, if customer invokes values() method on the above map, it prints ConverterCollection{null, null}. Calling containsValue(null) on above map prints false in 12.1.2 whereas it prints true in 3.5.3.x.  The containsValue(null) should actually return true, as the map has null values, but somehow in 12.1.2 it returning false.
