Hi Yasumasa,
I think you could create an extension of LingeredApp with the "-Xcomp"
option or the "-XX:CompileCommand=compileonly,<method name>" option to
ensure JIT-ing of a method and maybe turn off TieredCompilation using
"-XX:-TieredCompilation" for ease, too. If that proves to be too
cumbersome, the JShell test case can still be used as a fallback option.
I agree with the possibility of JShell implementation change in the
future. But I might say it is better to have the test running till
however long it can, rather than not having any testing done for that
part at all.
Thank you,
Jini.

Hi Jini,
Thank you for sharing the testcase.
However I concern about this as below:
1. This bug appears at JIT'ed frame. So it might not appear on test server.
We can add -Xcomp or JSON for compiler control for this issue, but we
cannot control compile level (TieredCompilation) AFAIK.
2. If JShell implementation is changed in the future, this testcase
might not verify this bug.
I will merge your testcase to the webrev if these concerns can be ignored.
Thanks,
Yasumasa

Apologize for the delay in responding to this, Yasumasa.
I tried my hand at creating a test case for this by attaching an SA
process to jshell and by invoking a method to traverse the frame
oopmaps for the 'output reader' thread -- Please do take a look at:
http://cr.openjdk.java.net/~jgeorge/sponsorships/8187402_ysuenaga/TestFrameOopMap.java
<http://cr.openjdk.java.net/~jgeorge/sponsorships/8187402_ysuenaga/TestFrameOopMap.java>
I think, in general, for the issues manifested through the GUI, we
can probably try having unit test cases directly invoking the
methods involved.
Thanks,
Jini.

Hi Jini,
IMHO this issue (JDK-8187402) and JDK-8187403 are too difficult
to crate test cases because they are problems in Stack Memory
window in HSDB.
Can we add noreg-hard label to JBS?
Thanks,
Yasumasa

Hi Yasumasa,
The changes look fine, but please do include the test case
also for
this. In general, it would be great if you could provide
test cases also
along with the code changes while sending for review.
Thank you,
Jini.

I cannot access JPRT. So I need a sponsor.
