RE: [ajdt-dev] AJDT speed with multiple projects

["Sebastien Tardif" <stardif@xxxxxxxxxxxx>]

It seems that AJDT 1.4.2.200705221209 was released before AspectJ 1.5.4
is released so that what is known to be fixed in AspectJ 1.5.4 may not
be included in 1.5.4.200705211336.

We have 22 projects in our workspace. The projects are dependents like a
tree, so some depend of x projects and those x projects may depend of
others. We have no circular references.

In the trace below, only a Java file was modified by adding a space so
the resulting *.class should be the same then there is no point to
involve the dependents. Do you agree? Do we already have a bug logged or
it's already fixed?

We also notice that full build is often done when we expect incremental
build. 

We also see that AspectJ compiler is keeping a big chunk of
WeakReference that take around 800 megs in our RAD. One our developer
said that if we call org.aspectj.weaver.Dump.reset() the leak will go.
800 megs just for the AspectJ compiler is close to the limit a JVM can
have on Windows so we cannot extend our JVM memory allocation.

My team is complaining to me after I introduced AJDT in our big
government project.

Anyone is using AJDT on big software with multiple projects in the same
workspace?

What's the best practice to use AspectJ with Eclipse/RAD without AJDT?

I'm not planning on upgrading the Eclipse 3.2 version of AJDT any time
soon - but as far as I am aware it includes all the optimizations that
are in the later versions, so it wouldn't change your situation.

How are your projects dependent?  Just a big stack of AJ projects that
depend on each other?
