Details

    Description

      To verify that an object can be serialied the function ObjectMapper#canSerialize() is called. The internal implementation of this function synchronizes on an internal cache object etc. That causes in high load scenarios some performance issues.

      They (i.e. Jackson) does not recommend to use that function, because it is not easy to figure out reliably whether value of given type can be handled. They even are going to remove the function in one of the next releases [2].

      AT:

      • remove the function call ObjectMapper#canSerialize()
