Re: [Springframework-developer] AOP Performance Comparisons

[<jue...@we...>]

It would be great to fix this until the weekend, to allow for the 1.1.3 =
release to happen next week. Unfortunately, Rob is away for a couple of =
days, if I recall correctly. Rod, do you maybe have a chance to look at =
this, in particular if Rob doesn't?

Betreff: RE: [Springframework-developer] AOP Performance Comparisons



Rob,

I entered a bug in JIRA for the frozen flag and assigned it to Rod
initially. So if you fix this, could you please have a look at JIRA and
fix the corresponding bug?

Thanx,

Alef
