[aspectj-users] LTW: aspectj 1.7, caching weaving code. Needs clarificat

[Pasturel <jean-louis.pasturel@xxxxxxxxx>]

Since AspectJ 1.7.0+, we can enable LTW byte-code  caching by using the 
2 system properties :

    -Daj.weaving.cache.enabled=true
    -Daj.weaving.cache.dir=/tmp/aspectj-cache/ ( for DefaultFileCacheBacking implementation )

as bug report says, this caching is interesting, when the cache is 
filled at the first startup,  for the next start-up (faster), and also 
memory consumption.

I have a request, for the case of changing the LTW Aspect between 2 
startup ( development, stressing tests ...) , to have the possibility of 
cleaning the cache at every start up by adding and coding for example
-Daj.weaving.cache.cleanatstartup=true ( false by default)
Does it make sense ?

I wasted time to find why i raised NPE exception for an old LTW aspect 
!! Cleaning the cache solved the problem.
