-----------------------------
Assignee: Alex Rudyy (was: Keith Wall)
> "SEVERE: RuntimeException while executing runnable" reported by Guava to
> stderr if a state transition method throws exception
> -----------------------------------------------------------------------------------------------------------------------------

> Key: QPID-7623
> URL: https://issues.apache.org/jira/browse/QPID-7623
> Project: Qpid
> Issue Type: Bug

> As reported in QPID-7311, a state change that throws an exception, may cause
> a warning like the following to be reported to stderr:

> The problem is a general one rather than being specific to SSTS.
> The create exception handler involved code at lines
> AbstractConfiguredObject.java:1083 unconditional re-raises the exception.
> The exception then goes uncaught and is logged by Guava at line
> ExecutionList.java:160. Guava's behaviour here is documented in
> ListenableFuture.java:103.
> Whilst ugly, this actually causes no functional harm. The child creation
> error is still reported to the end user, and the child is still deregistered
> from the parent. However, the appearance of the stack on stderr will cause
> alarm to end-users.
> The cause of the problem is AbstractConfiguredObject.java:1083. The
> {{FutureCallback#onFailure}} impl should not be rethrowing the exception.
> Setting returnValue's exception is sufficient.
