APAR status

• Closed as program error.

Error description

• When 2 ruleflows are sharing a package using the sequential
  algorithm,
  a NullPointerException in com.ibm.rules.engine.fastpath.
  compiler.SemSequentialCompiler.visit(SemSequentialCompiler.java:
  378) (ODM 8.8.1)  is thrown when exporting a ruleset archive.
  There is a non initialized variable in the code which causes
  the issue.
  

Local fix

• It is possible to avoid the issue by switching to Fastpath as
  opposed to Sequential algorithm for the rule task.
  On the tasks that use the share rules, could you try changing
  the
  algorithm to Fastpath or to use the static rule ordering with
  Rete (i.e.
  the issue seems to be related to the Sequential algorithm).
  

Problem summary

• There was a non-initialized variable in the code that caused a
  Null Pointer exception to be thrown when 2 ruleflows shared a
  package using the sequential algorithm
  

Problem conclusion

• The code was fixed
  

Temporary fix

• It is possible to avoid the issue by switching to Fastpath as
  opposed to Sequential algorithm for the rule task.
  On the tasks that use the share rules, could you try changing
  the
  algorithm to Fastpath or to use the static rule ordering with
  Rete (i.e.
  the issue seems to be related to the Sequential algorithm).
