How to get JMS Serializer to throw an exception when deserializing JSON instead of coercion types?

Question

I am trying to write a REST API that uses JSON from a PUT request in Symfony2. JSON deserialization to work with an entity - but the JMS Serializer seems to force types from JSON instead of throwing an exception if the property type in JSON does not match the corresponding property of the objects.

For instance...

{ "id" : "123" }

... will lead to ...

int(123)

... if the property is iddefined as an integer in the entity.

But I would like JMS Serializer to throw an exception. Does anyone know how to achieve this?

Update 2016-02-27

One problem with the JMS Serializers type processing I found is this:

{ "id" : "n123" }

will lead to ...

int(0)

which is completely undesirable.

Can someone point me in the right direction?
