Now we are faced with the need to also include a java version of on of our assemblies and are unsure how we should go about integrating the building of this java source into MSBuild.

In Java 6 I can use a technique like this: @Deprecated public final class Test { public static void main(String[] args) { System.out.println(Test.class.isAnnotationPresent(Deprecated.class)); } } to decide if a type is deprecated.

This will inject an instance of an Instrumentation class into the static premain method.

It seems that log4j has some class loading issues (among others) and it seems to me the trend is to move out of log4j toward slf4j. (Hibernate stopped using the first in favor of the latter) Is it true? What are the main issues in log4j that slf4j solves? Is slf4j the final word or is there even a better "the next next log4j" industry ...
