[jira] [Resolved] (IGNITE-4298) User exceptions cause
IgniteException if Ignite services are deployed separately

> User exceptions cause IgniteException if Ignite services are deployed separately

> Key: IGNITE-4298
> URL: https://issues.apache.org/jira/browse/IGNITE-4298
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 1.7
> Reporter: Ben
>
> 2 services, Service A and Service B, are deployed and restricted to individual nodes. If A calls a method of B thru the service proxy and a user exception is thrown inside that method, then an IgniteException is thrown due to an InvocationTargetException. See code below for a reproducable example.
