<p>The full list of resolved issues in 1.9.3 is available 
<a href="https://bugs.eclipse.org/bugs/buglist.cgi?bug_status=RESOLVED&bug_status=VERIFIED&bug_status=CLOSED&f0=OP&f1=OP&f3=CP&f4=CP&j1=OR&list_id=16866879&product=AspectJ&query_format=advanced&target_milestone=1.9.3">here</a></h2>.</p>

<p>AspectJ 1.9.3 supports Java12. Java12 introduces the new switch expression syntax, but you must activate support for that via 
an <tt>--enable-preview</tt> flag when using the compiler and attempting to run the resultant classes:

Here is <tt>Switch3.java</tt>:
<pre><code>
=========8<=========
public class Switch3 {
	public static void main(String[] argv) {
		System.out.println(one(Color.R));
		System.out.println(one(Color.G));
		System.out.println(one(Color.B));
		System.out.println(one(Color.Y));
	}

	public static int one(Color color) {
		int result = switch(color) {
		 case R -> foo(0);
		 case G -> foo(1);
		 case B -> foo(2);
		 default -> foo(3);
		};
		return result;
	}
	
	public static final int foo(int i) {
		return i+1;
	}
}

enum Color {
	R, G, B, Y;
}

aspect X {
	int around(): call(* foo(..)) {
		return proceed()*3;
	}
}
=========8<=========
</code></pre>

Compile it with:
<pre><code>
$ ajc --enable-preview -showWeaveInfo -12 Switch3.java

Join point 'method-call(int Switch3.foo(int))' in Type 'Switch3' (Switch3.java:12) advised by around advice from 'X' (Switch3.java:30)

Join point 'method-call(int Switch3.foo(int))' in Type 'Switch3' (Switch3.java:13) advised by around advice from 'X' (Switch3.java:30)

Join point 'method-call(int Switch3.foo(int))' in Type 'Switch3' (Switch3.java:14) advised by around advice from 'X' (Switch3.java:30)

Join point 'method-call(int Switch3.foo(int))' in Type 'Switch3' (Switch3.java:15) advised by around advice from 'X' (Switch3.java:30)

</code></pre>

Now run it:
<pre><code>
$ java --enable-preview Switch3
3
6
9
12
</code></pre>
