aah! good thing. so the only left is "acl" that should be reported (so GC could find it). In HLO the instruction for "acl" is: I26:ldind.unc:o [t15] ((t9,t13)) -) t16:cls:ClTest$MyObject I can attach my log to JIRA if it makes sense. > In the log for the GCMap codegenerator's stage base is always '-1' and this > is correct (I can explain why if needed).

Hm, is there any reason I thought Jitrino is not like that?... So, the only way to detect all reported objects on a call-site is to stop on the call-site at runtime during enumeration? Not impressed. Does it log to the runtime log (rt.log) currently? I tried "-Djit.log=rt", but it produced no result.

I cannot see it in the logs.
