No, I checked and it was added in JMX 1.2.

One big hack you can do is to find the jmx 1.1 jar in WS, and replace
it with a jmx 1.2, provided you rename the jmx 1.2 with the same name
of the 1.1, making the server think it's using 1.1 while instead is
using 1.2.
Of course this suggestion is only for your experiments, cause a) I
have no idea if it works, b) it will certainly break the support (if
any) for WS, c) it may cause WS to not work, d) surely it's not
something I would recommend if not for experiments and e) I do not
have any responsibility this causes your hard-disk to be erased :)

You can try it just for curiosity.

I anyway suggest you use another app server if you can, one that is
up-to-date with the JMX API.
