[jira] [Created] (IGNITE-4298) User exceptions cause
IgniteException if Ignite services are deployed separately
Ben created IGNITE-4298:
---------------------------
Summary: 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.
{code:title=MyUserException.java|borderStyle=solid}
package com.example.testing;
public class MyUserException extends Throwable {}
{code}
{code:title=MyCounterService.java|borderStyle=solid}
package com.example.testing;
public interface MyCounterService {
int increment() throws MyUserException;
}
{code}
Note this error condition in the deployment of the two services: {{ignite.cluster().forYoungest()}}
