Embedding contents of a method in a log or report

In Java, is there a generic way to embed the code of a method in a log by any means? I am working in Cucumber and altough its tending towards (or is?) bad practice, the compliance department wants to see the assertions behind a "Then" statement printed out in the report (they cant access the source code). Writing to a log is the easy part, but how can i read everything in a method behind a "@Then" in a generic way?

So just to give you an idea of an example method:

 @Then("^my profile information is retrieved with success")
    public void validateProfileInformation() {
     assertThat(..).isEqualTo(..);
     assertThat(..).isEqualTo(..);
     assertThat(..).isEqualTo(..);
     assertThat(..).isEqualTo(..);
     assertThat(..).isEqualTo(..);
     assertThat(..).isEqualTo(..);
     if (this){
        x = y;
     }
}

What needs to be written in the log:

 SOME HEADER TEXT
 assertThat(..).isEqualTo(..);
 assertThat(..).isEqualTo(..);
 assertThat(..).isEqualTo(..);
 assertThat(..).isEqualTo(..);
 assertThat(..).isEqualTo(..);
 assertThat(..).isEqualTo(..);
 **Optionally:**
 if (this){
    x = y;
 }

So i really need the unexecuted code, dont need the outcome. Preferably like a generic method or interceptor, so that it can be applied accross the project, rather than having to add it to each method. A push in the right direction would be appreciated.
