RFR(XS): 8215966: GeneratePropertyPassword.sh uses bash syntax (was Re: [PATCH] JDK-8025886: Replace [[ and == bash extensions in tests)

[Sergei Ustimenko]

Hi Paul,

Thanks for taking care of this and for your time!

Agree, initial patch was mainly about forward porting
lost changes as you've just mentioned.

Regarding filling another RFE as I don't have a JBS account it
would be a bit of a trouble for me I guess. I could try my best at
https://bugreport.java.com/bugreport/ though I guess that's
not the right place for it. So if I may borrow a bit more of your
time, could you please help me with filling the RFE? I guess missing
shebang is not critical, but might lead to a nasty situation.

Thanks,
Sergei
