[jira] [Created] (HADOOP-7695) RPC.stopProxy can throw unintended exception while logging error

RPC.stopProxy can throw unintended exception while logging error
----------------------------------------------------------------

                 Key: HADOOP-7695
                 URL: https://issues.apache.org/jira/browse/HADOOP-7695
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc
    Affects Versions: 0.24.0
            Reporter: Aaron T. Myers
            Assignee: Aaron T. Myers
             Fix For: 0.24.0


{{RPC.stopProxy}} includes the following lines in case of error:

{code}
LOG.error("Could not get invocation handler " + invocationHandler +
          " for proxy " + proxy + ", or invocation handler is not closeable.");
{code}

Trouble is, the {{proxy}} object is usually backed by {{WritableRpcEngine}}, which will fail in the event {{toString}} is called on one of its proxy objects. See HADOOP-7694 for more details on that issue. Until that's addressed, we might as well change the log message in {{RPC.stopProxy}} to not call {{toString()}} on {{proxy}}.
