I tried this with JDK 11, 17 and 19 and don't see any significant 
difference in the co-location. When you do "next" then  JDI will get 
events related to VM callout to checkPackageAccess. With JDK 11 I see 3 
co-located events (2 entry, 1 exit) for the main thread. The libs code 
has changed a bit since then and for JDK 17 and 19 there are 5 
co-located events (4 entry, 1 exit). I don't recall seeing anything go 
by that changed the code that decides if events are deferred. I think 
Chris is right that if there was something was broken then there would 
be test failures and bug reports. So I guess the question is whether the 
co-location with this example does reflect what you are seeing or if 
there is something else going on.
