-----------------------------------------
Summary: All binary types are registered twice
Key: IGNITE-12479
URL: https://issues.apache.org/jira/browse/IGNITE-12479
Project: Ignite
Issue Type: Bug
Components: binary
Reporter: Denis Mekhanikov
Assignee: Denis Mekhanikov
Fix For: 2.8
When a POJO is put into a cache, its binary type is registered twice during
marshalling.
Example:
{code:java}
public class MetadataRegistrationExample {
public static void main(String[] args) {
Ignite ignite = Ignition.start("config/ignite.xml");
Person p = new Person("Denis");
ignite.getOrCreateCache("cache").put(1, p);
}
static class Person {
private String name;
public Person(String name) {
this.name = name;
}
}
}
{code}

You can see, that a type is registered twice. First it's registered without any
fields, and only the second time the type is registered properly.
