Re: [Springframework-developer] Simplification of Spring JMX

[Rob H. <ro...@ca...>]

I'm getting it ready for 1.2 - not sure when that will be though. I 
would guess late December at the earliest.

I still have to include JSR-175 support and a couple of other little 
features but I fixed quite a few problems yesterday and moved many of 
the concepts more inline with those already existing in Spring. I'm also 
going to try for compatibility with 1.0 as much as possible which might 
mean refactoring the proxy classes a little since they rely on some 1.2 
specific interfaces to support JSR-160 proxies.
