NPE In TypeFactory. constructParametricType(...)

[ctytgat]

Used version: 2.9.0

We've got some code that executes:

new ObjectMapper().getTypeFactory().constructParametricType(List.class, HashMap.class);

This throws a NPE, depending on whether or not the type info is cached. Can easily be reproduced by executing just this statement.

Exception in thread "main" java.lang.NullPointerException
