APAR status

• Closed as program error.

Error description

• The error message can be misleading, such as:
  GBRSM0276E: An
  unexpected error occurred while exporting ruleset archive - B2X
  migration failed. java.lang.NullPointerException
  
  But when
  adding the option -ea in the eclipse.ini file (to enable
  assertions), the error message becomes:
  An internal error
  occurred during: "Export ruleset archive".
  Variable
  java.util.Date past183daysAgo202980 = subtract_duration_to_date(
  this#com.ibm.rules.generated.fastpath.AbstractFastEngine#.engine
  Data.currentDate, 183, com.wkhealth.ce.utils.TimePeriod.DAYS)
  not declared in scope
  
  This error may occur when two variables
  (in two different rules) are initialized with the same value
  (more precisely when they refer to the same object).
  

Local fix

• This problem only occurs when using the "Fastpath" algorithm, so
  changing to "Sequential" instead solves it.
  Please notice that the problem can be happening when building a
  different ruleflow than the one selected for the ruleset (all
  ruleflows are built). So you might need to change the algorithm
  for all the ruleflows.

  * USERS AFFECTED:                                              *
  * Rule Designer users exporting rulesets with engine in        *
  * Fastpath mode.                                               *

  * PROBLEM DESCRIPTION:                                         *
  * Rulesets that have rules containing a variable initialized   *
  * to the same object not handled properly with Fastpath.       *

  * RECOMMENDATION:                                              *

Problem conclusion

• The code was fixed.
  

Temporary fix

• Change engine to "Sequential" mode.
