PROBLEM
By default, the generated Java class prints the memory address when toString() is invoked.
However, sometimes it is helpful to have a more meaningful toString() for debugging purposes.
SOLUTION
To fix this, configure maven-jaxb2-plugin to generate toString() based on the fields in the class:-
