---------------------------------------------

Valentin,

Do you know any possible scenario for such situation? I can reproduce it with synthetic test only.

> If {{typeId==0}} and full class name is written in the binary format, {{BinaryType.isEnum()}} method fails with the exception:
> {noformat}
> Caused by: org.apache.ignite.binary.BinaryObjectException: Failed to get binary type details [typeId=0]
>   at org.apache.ignite.internal.binary.BinaryTypeProxy.target(BinaryTypeProxy.java:99) ~[ignite-core-1.6.7.jar:1.6.7]
>   at org.apache.ignite.internal.binary.BinaryTypeProxy.isEnum(BinaryTypeProxy.java:86) ~[ignite-core-1.6.7.jar:1.6.7]
> {noformat}
> This happens because {{BinaryTypeProxy.target()}} method ignores this case. If {{typeId==0}}, It should look up full class name from the object and convert it to the actual type ID before trying to fetch metadata.
