Vladimir Sitnikov updated CALCITE-4319:
---------------------------------------
    Description: 
{code:java}    VolcanoRuleMatch match = ruleQueue.popMatch(
        Pair.of(rel,
            m -> m.getRule() instanceof ConverterRule
                && 
m.getRule().getOutTrait().satisfies(group.getTraitSet().getConvention())));
{code}

satisfies(null) fails with NPE
