more funny log entries

[Kirk Pepperdine]

Hi all,

I found this…

young with initial-mark
followed by a Full GC
in the middle of a complete concurrent mark cycle…

Looks like the Full GC didn’t interrupt the concurrent mark cycle. Is that a reasonable assumption?

java -version
1.7.0_51-b13 running on OSX (Mavericks)

Regards,
Kirk
