I'm seeing an occasional NPE in our tests, it only happens every so often, I fear this might be a concurrency bug. Note, the same message is deseralized 3 times simultaneously with the same ObjectMapper instance.

java.lang.NullPointerException: null

The json is

"{"origin":{"number":"40411","id":1},"command":"post","user":{"userName":"bobthebuilder","lastChange":0,"createTime":0,"id":1},"placeCode":{"loca":"loca","id":1},"processed":"hello
