Apache Ignite: Failed to create string representation of binary object

Question

I am getting below exception and not able to figure out what is wrong with the code.

I have simplified my pojo classes which are to be persisted to ignite cache, but still the complexity remains.

All my pojos are serializable but few of them have business logic code, dao, application context object. These objects can't be removed. Removing these things from the code will require whole code refractoring.

Any help is appreciated

Answer 1

In this case you should disable DEBUG logging. DEBUG logging will sometimes try to call toString on objects that does not need to be deserialized (and present as classes) otherwise.

Change global log level to INFO to make this issue go away.
