-------------------------------------------
Summary: GraphStep clone() doesn't leaves references to the
original iteratingSupplier
Key: TINKERPOP-2595
URL: https://issues.apache.org/jira/browse/TINKERPOP-2595
Project: TinkerPop
Issue Type: Bug
Components: process
Affects Versions: 3.4.12
Reporter: Stephen Mallette
{{GraphStep}} retains the {{iteratingSupplier}} from the object it cloned.
Typically, this is no problem because at strategy application a graph will
replace {{GraphStep}} with its own implementation (e.g. TinkerGraph does this
with {{TinkerGraphStep}}). However, if it is not replaced that
{{iteratingSupplier}} will refer to the one from the original {{GraphStep}} and
if strategies have not been applied and if that {{GraphStep}} belonged to an
anonymous traversal, it will put the clone in a state where it will try to
access {{EmptyGraph}} rather than the graph instance expected.
