LocalVariableTable is missing for methods adviced by around execution though that is generated for before execution.
So softwares those get method parameter information from class files (such as java2wsdl or eclipse ide) can't get the information.


Here is the class which has method advied by two aspects.

public class Test{
	public void sayHello(String message){
		System.out.println(message);
	}
}

The aspect(1) which contains "around execution".

public aspect TestAroundAspect{
	void around(): execution(void Test.sayHello(String)){
		proceed();
	}
}

The aspect(2) which contains "before execution".

public aspect TestBeforeAspect{
	before(): execution(void Test.sayHello(String)){
	}
}

And here are the results generated by ajc and javap.
