Hi Serguei,

thanks a lot for sponsoring this change. It seems that https://bugs.openjdk.java.net/browse/INTJDK-7609362 is not visible. Could you please make it readable for everybody. Since it is filed on an internal test suite it’s not possible to make the bug visible to everyone. OK, thanks. I mis-read Serguei's mail. I thought he wanted to create a jdk regression test (altough that's a little complicated because of the need to create a native shared library).

Yes, that is the root problem. Working on fixing it…

It adds code to iterate over the slots of the expression stack. Found object references are used as heap roots, the same way as object references in locals slots.
