From this post on the Eclipse AJDT forum: http://www.eclipse.org/forums/index.php/t/369503/

When softening exceptions, AspectJ doesn't seem to soften the exception thrown by the automatic close() invocation when using the try-with-resources syntax introduced in Java 7 (often an IOException).  eg:

---
In Java code:

try (BufferedReader reader = new BufferedReader(new FileReader("test.txt"))) {
  System.out.println(reader.readLine());
}


In AspectJ code:

declare soft: IOException: within(*)

---
The above will result in a compilation error, "Unhandled exception type IOException thrown by automatic close() invocation".

A workaround is to add a catch for the IOException, or to add a throws clause to the method, which kind of makes the exception softening somewhat redundant.

If you're using AJDT, doing these workarounds then adds AJDT add markers to the try-with-resources block, one of which looks like it's for the automatic close() - maybe the 'unhandled exception' error is preventing AspectJ from properly softening the exception?
