RS03942: INVALID ASSERTION IN RETE

APAR status

• Closed as program error.

Error description

• When assertions are enabled, the execution of a ruleset may fail
  with an AssertionError for some specific rules, when using the
  Rete algorithm.
  
  The stack trace of the exception is:
  
  Exception in thread "main" java.lang.AssertionError
  at com.ibm.rules.engine.rete.runtime.network.impl.IlrExistsObje
  ctJoinNode.update(IlrExistsObjectJoinNode.java:223)
  at com.ibm.rules.engine.rete.runtime.network.impl.IlrAbstractOb
  jectMemNode.notifyUpdate(IlrAbstractObjectMemNode.java:63)
  ...
  

Local fix

• This error is a false positive. The execution completes normally
  when disabling the assertions.

  * PROBLEM DESCRIPTION:                                         *
  * The assertions code checked that the RETE algorithm          *
  * invariants were satisfied for the exists condition of rules, *
  * which led to a false assertion violation that stops the      *
  * execution of the rule engine.                                *
