Intellij Structural Search: How to find empty try catch blocks?

Question

How can i find the empty try catch blocks?

Using the Copy existing template... I found the structural search for try catch:

try {
  $TryStatement$;
} catch($ExceptionType$ $Exception$) {
  $CatchStatement$;
}

I want to enhance it so that it does only find try catches with empty catch blocks

It should find:

 try {
        assertTrue(output.validate());
    } catch (Exception e) {
        //TODO something
    }

or

    try {
        assertTrue(output.validate());
    } catch (Exception e) {

    }

or

try {
        assertTrue(output.validate());
    } catch (Exception e) {}

However not:

 try {
        assertTrue(output.validate());
    } catch (Exception e) {
        e.printStackTrace();
    }

Right now it obviously finds both since there's no differentiation betweens. How can I add this extra check?

Instead of using structural search, you could also do: Analyze / Run Inspection by Name / Empty 'catch' Block — Jesper, Jul 14 '16 at 06:28
thx, but it does not find the empty catch with commentar, like in first example. — user1167253, Jul 14 '16 at 06:58
The *Empty 'catch' block* inspection has an option to count comments as content which you can disable. — Bas Leijdekkers, Jul 14 '16 at 08:21

Use the template you have found and on CatchStatement variable set Min count and Max count to 0.
