Dylan Werner-Meier updated TINKERPOP-2858: ------------------------------------------ Description: I encountered a "ConcurrentModificationException" during a particularly difficult Gremlin query, on this specific line of code: {code:java} currentStep.getLabels().forEach(currentStep::removeLabel); {code} ( [ConnectiveStrategy.java:98|https://github.com/apache/tinkerpop/blob/3.6-dev/gremlin-core/src/main/java/org/apache/tinkerpop/gremlin/process/traversal/strategy/decoration/ConnectiveStrategy.java#L98] ) "currentStep.getLabels()" is a "LinkedHashSet", and it doesn't support concurrent iteration and modification. Proposed fix: add a "clearLabels()" method to "AbstractStep". was: I encountered a `ConcurrentModificationException` during a particularly difficult Gremlin query, on this specific line of code: {code:java} currentStep.getLabels().forEach(currentStep::removeLabel); {code} ( [ConnectiveStrategy.java:98|https://github.com/apache/tinkerpop/blob/3.6-dev/gremlin-core/src/main/java/org/apache/tinkerpop/gremlin/process/traversal/strategy/decoration/ConnectiveStrategy.java#L98] ) "currentStep.getLabels()" is a "LinkedHashSet", and it doesn't support concurrent iteration and modification.
