Bug Or 'Feature' witn Kotlin 1.4   + Jackson 2.11

Updateing code previously compiling with Kotlin 1.3.61 , Jackson <http://2.9.to|2.9.8  to> Kotlin 1.4 + Jackson 2.11

This Java function
```public &lt;T extends JsonNode&gt; T set(String fieldName,
                                  JsonNode value)```
Is throwing off Kotlins type inference for expressions like

        val node : ObjectNode = /// assign
        val value : JsonNode  = // assign

       node.set("field" , value )

    and
        node["field"] = value

The error is cannot determine type for type parameter T
 I can get the former to work with
          node.set&lt;JsonNode&gt;( "field", value )

I have not gotten the later to work at all -- I dont know how to explicty type the fun  type parameters to an operator overload
These lame attempts didnt work -- but I didnt expect them
         node&lt;JsonNode&gt;{"field" ] = value
         node([&lt;JsonNode&gt;) "field" ] = value

seems to be a fault on the Java function.

The Java function specifies a Type T, but never uses it in the function itself it seems.

This looks like a potential Kotlin regression in new type inference. Can you please report an issue at <http://kotl.in/issue> with self-contained code sample to reproduce. Thanks!
