I agree with you on both counts. Ctors are an excellent way of implementing dependency injection, and static methods aren't. However loggers are more of an aspect than a dependency. Absent some other framework (AOP, for example, or some sort of annotation processing), good old frameworks and libraries solve this problem. Have a look at Apache logging: <http://commons.apache.org/logging/>
