Hi David,

Looks like a bug. As a workar= ound, you can either use optimized marshaller or compare enum ordinal.
I've created an issue IGNITE-5087 [1].

Hi all,

I encounter= ed something weird about enum value in the object stored in ignite cache.

for example:

class definit= ion:
public class Application {
    p=
rivate long i=
d;
    privat=
e String name=
;
    private=
 ApplicationType type;
}
enum definition:
public enum A=
pplicationType {
    TX {
        @Override
        public boolean isSupported() {
            return true;
        }
    },
    API {
=
        @Override
        public boolean isSupported() {
            return true;
   =
     }
    };

    public abstract boolean isSupported();
}
then have a cache like:
IgniteCache<Long, Application> cache
When get back the Application instance from cache, the value of the type <=
/span>
property will not equal to the enum value=
 in the enum class, i found their
hash co=
de is different, even though they have same class name.
for example, 
Application app =3D =
new Application(1L, "app 1", App=
licationType.API);
app.getType() =3D=3D ApplicationType.API is true
a=
pp.getType().getClass().getName() is ApplicationType$2, hash code is 2=
51520863

Application appFound =3D cache.g=
et(app.getId());
appFou=
nd.getType() =3D=3D Application.API is false
appFound.getType().getClass().getName() is Appli=
cationType$2, hash code is 331596257

ApplicationType.API.hashCode() is 251520863

I tried an e=
num without any method definitions, then no issue. Any idea about this?

BRs,
David
