---------------------------------------
Summary: Failues in 'resolve-expression" op appear in server log
Key: WFCORE-149
URL:
https://issues.jboss.org/browse/WFCORE-149
Project: WildFly Core
Issue Type: Bug
Components: Domain Management
Reporter: Brian Stansberry
Priority: Minor
I happened to notice this in a server log:
11:53:48,854 ERROR [org.jboss.as.controller.management-operation]
(management-handler-thread - 3) WFLYCTL0013: Operation ("resolve-expression")
failed - address: ([]) - failure description: "WFLYCTL0211: Cannot resolve expression
'expression \"${unresolvable}\"' -- java.lang.IllegalStateException:
Failed to resolve expression: ${unresolvable}"
That failure shouldn't end up in the server log; it's just a client mistake
unrelated to server operation.
A guess is that it's logged because the OFE has the ISE attached as a cause, in which
case a simple fix is to not attach the ISE, which adds no value.
Note the handler has a catch block above the one that throws this OFE that handles a
SecurityException case. In that case it *may* be appropriate for something to appear in
the logs, assuming tracing how the SE can happen indicates it could be triggered by a user
fishing for an exploit. In that case a direct WARN in the log from the
ResolveExpressionHandler instead of attaching the SE to the OFE and letting the
OperationContext log an ERROR may be more appropriate.
