RFR: JDK-8155936: Boolean value should be set 1/0 or true/false via VM.set_flag jcmd

[Yasumasa Suenaga]

Hi all,

This review request relates to [1].

We can change a part of -XX option via VM.set_flag jcmd.
This jcmd requires 1 or 0 as boolean value.
However, we can set 0 or not (NOT 1).

In jinfo, we can set boolean value with 1/0 or +/-.
So I think it is useful if VM.set_flag accept boolean value in true/false.

I uploaded a webrev for this issue.
Could you review it?

I cannot access JPRT.
So I need a sponsor.


Thanks,

Yasumasa
