Reported by Eric on the mailing list but here is a crafted testcase:

--- Code.java
import org.aspectj.lang.annotation.*;

public class Code {
	public static void main(String[]argv) {
		fo();
		Boo.fo();
	}

	public static void fo() {
		System.out.println("xyz");
	}
}

@Aspect
class X {
	@Before("execution(* Code.fo())")
	public void foo() {}
	//before(): execution(* Code.fo()) { }
}

class Boo {
	public static void fo() {
		System.out.println("xyz");
	}
}
---

--- Y.java ---
aspect Y {
	before(): execution(* Bo*.*(..)) {

	}
}
---

ajc -1.8 Code.java -d out

ajc -1.8 Y.java -d out2

--- out2/META-INF/aop-ajc.xml ---
<aspectj>
<aspects>
<aspect name="Y"/>
</aspects>
<weaver options="-verbose -showWeaveInfo">
</weaver>
</aspectj>
---

java -javaagent:$ASPECTJ_HOME/lib/aspectjweaver.jar -classpath out:out2:$ASPECTJ_HOME/lib/aspectjrt.jar Code

gives:

Doesn't happen if it is a code style aspect (X)
