I've finally made it so I would like to share my solution. Maybe someone will need it some day.
I've decided to do the compile time weaving. In my last post I was very close to do it. The aspectj-maven-plugin was simply too old but when I've changed it to 1.4 the weaving process was ok but... not for the CDI:
The problem was finally solved in the AspectJ 1.6.12 (you can find details here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=349149) with the new option of ajc tool which is:
org.jboss.weld.exceptions.UnproxyableResolutionException: WELD-001437 Normal scoped bean class myPackageName.myClassName is not proxyable because the type is final or it contains a final method static final java.lang.String myPackageName.myClassName.myMethodName_aroundBody0(myPackageName.myClassName.,org.aspectj.lang.JoinPoint).
As far as I'm concerned it is not possible to use this option in the current (1.4) version of aspectj-maven-plugin but there is no such problem with ant 1.8.2.
The final solution is adding the following plugin to your <build> tag:
Now Spring Security works everywhere. The
<property name="compile-classpath" refid="maven.compile.classpath"/>
option is no longer needed.
