Re: [Springframework-developer] AOP Performance Comparisons

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

Jurgen/All,

Now that your back can we take a look at issue SPR-285 regarding no-arg 
constructor proxy creation? We need to decide how to modify 
ProxyFactoryBean to allow for the constructors args and types to be 
passed to Cglib2AopProxy. The issue contains more detail.

Also just committed an big fix for the frozen flag problem. Once 1.1.3 
is released I will send an updated Spring AOP test to the AWBench guys.

>>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?
