  • 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.                                *
    ****************************************************************
    * RECOMMENDATION:                                              *
