Hi Liu Xin,
No, this is not a wrong usage on your part. You are facing the following
issue:
https://bugs.openjdk.java.net/browse/JDK-8157947
So, at this point, till this is fixed, you would face issues if you try
to run commands based on the the javascript interface with jhsdb.
Thanks,
Jini.

Hello, serviceability mail-list,
Jdk9 refactored the CLI for hsdb. I try to catch you up. With the
latest openjdk9 build, I always meet the following message when I want
to use 'console' in GUI.
./jhsdb hsdb
//attach pid
//windows/console
javax.script.ScriptException: TypeError: sapkg.runtime.VM.getVM is not a
function in sa.js at line number 54
Warning! JS Engine can't start, some commands will not be available
I quickly look at it. It seems that it has problem to load 'sa.js'.
// SA singletons are kept in 'sa' object
var sa = new Object();
sa.vm = sapkg.runtime.VM.getVM();
sa.dbg = sa.vm.getDebugger();
sa.cdbg = sa.dbg.CDebugger;
I strongly suspect that it didn't invoke
sun.jvm.hotspot.runtime.VM.initialize before loading the sa.js.
is it intentional or just wrong usage of mine?
Please note that I did build nashorn and jjs works perfectly. I can
reproduce this problem on linux and macosx.
I took reference of the doc of clhsdb shipping with hotspot source code:
hotspot/src/jdk.hotspot.agent/doc/clhsdb.html
is it out of date? I found it NOT 'Few CLHSDB commands are already
implemented in JavaScript.'
thanks,
