Hi Yasumasa,
Thank you for the update!
A couple of suggestions:
213 * This method converts jhsdb-style options (oldArgs) to oldfashioned
Replace: "oldfashioned " => "old fashioned".
There are several occurrences of it.
214 * style. SALauncher delegates the work to the entry point of each tools.
Replace: "each tools" => "each tool"
225 * You also can set the options which cannot be map to oldfashioned
226 * arguments. For example, `jhsdb jmap --binaryheap` cannot be map to
Replace: "cannot be map" => "cannot be mapped"
231 * This method returns the map which the key is oldfashioned option,
232 * the value is its value.
I'd suggest to say:
* This method returns the map of the old fashioned key/val pairs.
This loop still needs to be commented:
242 while ((s = sg.next(null, longOpts)) != null) {
243 var val = longOptsMap.get(s);
244 if (val != null) {
// What is done here and why?
245 newArgMap.put(val, null);
246 } else {
247 val = longOptsMap.get(s + "="); // Why the "=" is added
248 if (val != null) {
// What is done here and why?
249 newArgMap.put(val, sg.getOptarg());
250 }
// Why there is no else statement, do we just skip the
option?
251 }
252 }
Such comments will give more context and make this code more readable.
Thanks,
Serguei

Hi Serguei,
I added the explanation as a comment in parseOptions what is longOptsMap,
and how parseOptions() work in new webrev.

I'm not good at English, so comments are welcome :)
Thanks,

Hi Yasumasa,
In fact, I have a problem to understand what the parseOptions()
method is doing.
Could you add necessary comments explaining what is done in the loop?
I'm sure I'll be not alone in having trouble to read this code.
Also, it is not clear the approach with the longOptsMap's.
Why do you need to map "exe=" to "exe" but "mixed" to "-m"
and"clstats" to "-clstats"?
It is better to be explained in the parseOptions() method as well.
Thanks,
Serguei

Hi all,
Please review this change:
JBS: https://bugs.openjdk.java.net/browse/JDK-8226204
webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8226204/webrev.00/
This enhancement has been proposed in [1].
SALauncher (jhsdb implementation) processes the option for each
subcommand (e.g. jstack, hsdb).
But they exist in many place with similar code.
So there is some room for refactoring.
This change has passed the tests on submit repo and
serviceability/sa tests.
Thanks,
Yasumasa
