How to avoid "exception is never thrown" when commenting out a line while debugging

+7

I have a code block like this:

try {
    ...
    x.foo(); // This is the line that forces us to have the try block
    ...
} catch (ArrayIndexOutOfBoundsException e) {
    logger.error(e.getMessage(), e);
}

x.foo() is the line that is potentially throwing the exception.

Let's say that I am debugging the above block, and I want to comment out that line. What happens then is that I get this:

error: exception ArrayIndexOutOfBoundsException is never thrown in
       body of corresponding try statement

My question is how to handle this in a convenient way while debugging. I know how to rewrite it properly when I'm done debugging. But it is extremely annoying to to repeatedly remove and restore the try and catch lines just because I want to temporarily disable a line.

While writing the question I actually came up with something that seems to work fairly well, and it's very simple. Just add if(false) in front of the statement.
