How should the escape analysis results be interpreted?
“Can potentially escape” means that the analysis has found a path through which an object may escape. This does not necessarily mean that the object will escape, this may mean that there is a route of escape (even though that route might not be chosen at runtime, or possibly cannot be chosen at runtime). “Cannot escape” means that there is simply no route of escape possible, and the object will never escape no matter how the application is executed or how often.
