IC89755: NullPointerException in Streams Studio for Import operators whose output stream is not input by any operators.

 

APAR status

  • Closed as program error.

Error description

  • It is legal SPL code to have an Import operator with an output
    stream that that is not input by any operators.  If you submit
    the SPL application as a job, Streams Studio reports a
    NullPointerException when it refreshes the  information about
    the instance.  Additionally, when you attempt to view the
    application with the "Show Application Graph" command in
    Streams Studio, a NullPointerException occurs.
    

Local fix

  • To work around the problem, add an operator that takes the
    Import output stream as input. This operator can be just a
    temporary placeholder, for example, a Custom operator that does
    nothing with the input.  Alternatively, remove the Import
    operator from the SPL source code.
    

Problem summary

  • Users Affected:
    Developers who are using Streams Studio with an application that
    has an Import operator with no stream connections to any
    downstream operators.
    

Problem conclusion

  • Problem Conclusion:  This problem is fixed in Version 3.0 Fix
    Pack 1 and later fix packs.
    

Temporary fix
