Pavel created TINKERPOP-2585:
--------------------------------
Summary: Traversal failed for different strategies order
Key: TINKERPOP-2585
URL: https://issues.apache.org/jira/browse/TINKERPOP-2585
Project: TinkerPop
Issue Type: Bug
Affects Versions: 3.5.0, 3.5.1
Reporter: Pavel
Test randomly reproduced, empirically failed when PathRetractionStrategy apply
before InlineFilterStrategy
https://gist.github.com/mad/3027855063bed41bae0a2aa7d2051352
In real code strategies may change order during static vars initialized
