Hi all, I posted a message a few months ago entitled "Unable to create hprof heap dump from core file with jmap on Oracle Solaris" [1] to describe my difficulties creating a usable hprof heap dump from a core file with jmap with Java 8. Despite the fact that JDK-8044416 has been resolved, the problem still exists and has been reported by more users. While JDK-8044416 putatively fixed the issue by getting rid of the exception when invoking jmap, an hprof heap dump generated from a core file with Java 8 is still unusable in any of the major analysis tools. See Eclipse bugs 471757 [2] and 476262 [3] for details regarding Eclipse MAT in particular. I have also been unable to analyze an hprof heap dump generated this way in VisualVM. A user on Stack Overflow reports the same issue with YourKit [4]. The users mentioned above have reported this issue with core files generated on Linux, Windows, and Oracle Solaris -- and using Java 8 Update 60 or above, where this is supposed to be fixed. Clearly something is still not working as expected. Could we please get an update on when this issue will be resolved and how to track progress?
