Exception handling try catch inside catch

Question

I recently came across code written by a fellow programmer in which he had a try-catch statement inside a catch!

Please forgive my inability to paste the actual code

Answer 1

Here is a case :

try{
    //Dangerous Operation
} catch (AnyException ae) {
    try {
        //Do rollback which can fail
    } catch (RollbackFailedException rfe) {
        //Log that
    }
} finally {
    try {
        //close connection but it may fail too
    } catch (IOException ioe) {
        //Log that
    }
}

It's about the same thing as @x0n said. You might need to handle exception while try to close resources or while you're trying to resolve a situation brought by another exception.
