Method ignores exceptional return value : FindBugs

Question

Why the heading error in the findbugs for the following code.

 boolean isCreated =  folder.mkdirs();

    if (!isCreated) {
        throw new IOException("Folder already exists..!!!");
    }

Are you sure it's not coming from one of the other method calls on the folder object (presumably being a java.io.File instance). — Steve C, May 13 '14 at 13:10

According to Finds Bug Description.

Method ignores exceptional return value

Method returns a value that is not checked. The return value should be checked since it can indicate an unusual or unexpected function execution.

Probably because you're not checking for the SecurityException that mkdirs can throw.

This is plain wrong. Read the Bug Description, it has nothing to do with catching SecurityException. – Ilya Shinkarenko Jan 30 '17 at 16:15
