RFR: 8187402: UnknownOopException is occurred on Stack Memory window in HSDB

[Jini George]

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

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.
