PH40057: IBM ADDI ANALYZE CLIENT 6.0.0.0 GENERATES UNHANDLED EVENT LOOP EXCEPTION DURING EXPLORE OF PROJECT.

APAR status

• Closed as program error.

Error description

• Unhandled event loop exception message and
  java.lang.NoSuchMethodError generated when exploring project
  with multiple COBOL programs, when using ADDI 6.0.0.0 and IDz
  14.2.
  
  Error in .log file in Analyze Client has message similar to:
  
  !ENTRY org.eclipse.ui 4 0 2021-08-20 14:06:14.911
  !MESSAGE Unhandled event loop exception

  and each COBOL program in the list remains at "loading...#nn"
  

Local fix

• Renaming failing (newer) .jar files to allow those
  shipped with Analyze Client to be used instead is possible, but
  could cause unexpected results from non-Analyze Client
  applications in the IDz instance that depend on the newer
  versions of the .jar file(s).
  

Problem summary

• Analyze Client gets Unhandled event loop exception message,
  java.lang.NoSuchMethodError:
  org/eclipse/nebula/widgets/nattable/layer/LabelStack.addLabel
  exception in IDz log when trying to explore a program with
  multiple COBOL programs, and items in list of COBOL programs
  just say loading...#nn
  

Problem conclusion

• The solution was to add at AD level a version constraint for
  using the specific 1.4.0 nattable jar (provided by AD)
  

Temporary fix
