Upgrading Standard to Enterprise breaks .NET object method execution

We just upgraded our CF 10 Standard to CF 13 Enterprise over the weekend and are trying to hammer out some strange bugs.

One example is where we are hitting a .NET web service which returns an object. When we try to execute the .getString() method on this object the value returned is "undefined":

<cfset var recInfo = structnew()>

<cfset var schemaName = "">

<cfset var theArray = arraynew(1)>    

<cfinvoke webservice="#this.JobTicketWS#" method="GetSchemasNames" returnVariable="result" wsversion="1">

     <cfinvokeargument name="inUsername" value="#this.inUserName#">

     <cfinvokeargument name="inPassword" value="#this.inPassword#">

     <cfinvokeargument name="inTicketID" value="#arguments.jobTicketID#">

</cfinvoke>

<cfif result.getString() neq "">

     <cfset theArray = result.getString()>

     <cfset schemaName = theArray[1]><!--- if it's not empty it will always be 1 --->

</cfif>

What the value I am expecting is a single-dimension array of a string.

The error is "theArray is undefined" - when I explicitly dump #result.getString() I get "undefined"

I can execute another function on this very same object that returns a string and it works just fine. Only the methods that return an array that are breaking.

We're on Windows Server 2012 and apparently Java 10 after the upgrade. (we were on Java 😎 with a single CF node.

Any ideas are appreciated.

    FYI, somehow this one little change fixed the problem:

    WAS:

    <cfif result.getString() neq "">

         <cfset theArray = result.getString()>

         <cfset schemaName = theArray[1]><!--- if it's not empty it will always be 1 --->

    </cfif>

    NOW:

    <cfif len(result.getString()) neq 0>

         <cfset theArray = result.getString()>

         <cfset schemaName = theArray[1]>

    </cfif>    

    Somehow, CF sees a difference between an empty string and string of length 0.

    Moving on...and thanks.

    Carmen, what do you see if you just cf dump result. Getstring(), right after the cfinvoke? And then what about that, if anything, is shown in a dump of result itself?

      If I dump the result from the webservice call, I see object:

      getSchemaNames result - object of XMPieWSAPI.ArrayOfString
      Class NameXMPieWSAPI.ArrayOfString
      Methods
      Method Return Type
      equals(java.lang.Object)boolean
      getDeserializer(java.lang.String, java.lang.Class, javax.xml.namespace.QName)org.apache.axis.encoding.Deserializer
      getSerializer(java.lang.String, java.lang.Class, javax.xml.namespace.QName)org.apache.axis.encoding.Serializer
      getString()java.lang.String[]
      getString(int)java.lang.String
      getTypeDesc()org.apache.axis.description.TypeDesc
      hashCode()int
      setString(java.lang.String[])void
      setString(int, java.lang.String)void

      Immediately after the call I am dumping this:

      <cfdump var="#result#" label="getschemanames result">

      <cfif isArray(result.getString())>

           <p>an array!</p> <!--- this, of course, never hits --->

      </cfif>

      <cfoutput>

           <p>result.getTypeDesc() = #result.getTypeDesc()#</p>

      </cfoutput>

      <p>result.getString() = <cfdump var="#result.getString()#" label="result.getString()"></p><cfabort>

      Which results in this output:

      result.getTypeDesc() = org.apache.axis.description.TypeDesc@37fe0266

      result.getString() = undefined
