tracker issue : CF-4204716

Problem Description:

cfquery tag fails inside scheduled task with null message and null cause. This is happening for most but not all our scheduled tasks. Sometimes a restart causes a task to go from working to failing or failing to working. The particular SQL statement doesn't seem to matter - nor does it matter the datasource or whether the dbtype is query.

Steps to Reproduce:

Schedule a task using the below handler.cfc. Run the task from the CF Administrator. View test.log. Run test.cfm to invoke the task manually. View test.log.

handler.cfc
---------------

{code:java}
<cfcomponent implements="CFIDE.scheduler.ITaskEventHandler" output="false">
	<cffunction name="onTaskStart" access="public" output="false" returnType="boolean">
		<cfargument name="context" type="struct" />

		<cfreturn true />
	</cffunction>

	<cffunction name="execute" access="public" output="false" returnType="void">
		<cfargument name="context" type="struct" />

		<cflog file="test" type="information" text="execute start" />

		<cftry>
			<cfset local.query = queryNew("id") />

			<cfquery name="local.test" dbtype="query">
				SELECT id
				FROM query
			</cfquery>

			<cfcatch>
				<cflog file="test" type="error" text="execute catch: #serializeJSON(cfcatch)#" />
			</cfcatch>
		</cftry>

		<cflog file="test" type="information" text="execute finish" />
	</cffunction>

	<cffunction name="onTaskEnd" access="public" output="false" returnType="void">
		<cfargument name="context" type="struct" />

		<cflog file="test" type="error" text="onTaskEnd: #serializeJSON(context)#" />
	</cffunction>

	<cffunction name="onError" access="public" output="false" returnType="void">
		<cfargument name="context" type="struct" />

		<cflog file="test" type="error" text="onError: #serializeJSON(context)#" />
	</cffunction>

	<cffunction name="onMisfire" access="public" output="false" returnType="void">
		<cfargument name="context" type="struct" />

		<cflog file="test" type="error" text="onMisfire: #serializeJSON(context)#" />
	</cffunction>
</cfcomponent>
{code}


test.cfm
----------

{code:java}
<cfset handler = new handler() />
<cfdump var="#handler#" />
<cfset handler.execute({}) />
{code}

Actual Result:

Running the task from the administrator fails at the query tag with the following error. Running it manually from test.cfm runs without throwing an exception.

      "MethodName": "runFunction",
      "ModuleName": null
    },
    ...
  ],
  "Suppressed": []
}

Expected Result:

cfquery tag should behave the same everywhere regardless of whether it is run from a scheduled task

Any Workarounds:

None
