Stackoverflow when adding a larger list of property values using traverser.property()

Hey, we encounter a stack overflow:
Exception during Transaction, rolling back ...
org.apache.tinkerpop.gremlin.process.traversal.step.util.AbstractStep.hasNext(org/apache/tinkerpop/gremlin/process/traversal/step/util/AbstractStep.java:150): Java::JavaLang::StackOverflowError
    from org.apache.tinkerpop.gremlin.process.traversal.step.util.ExpandableStepIterator.next(org/apache/tinkerpop/gremlin/process/traversal/step/util/ExpandableStepIterator.java:55)
    from org.apache.tinkerpop.gremlin.process.traversal.step.sideEffect.SideEffectStep.processNextStart(org/apache/tinkerpop/gremlin/process/traversal/step/sideEffect/SideEffectStep.java:38)
    from org.apache.tinkerpop.gremlin.process.traversal.step.util.AbstractStep.hasNext(org/apache/tinkerpop/gremlin/process/traversal/step/util/AbstractStep.java:150)


when we try to add large list of values (~4000 entries) via a traversers property() calls. It seems the property method is implemented using recursion which causes the problem. See also https://github.com/JanusGraph/janusgraph/issues/3479 Is this a known issue?
