I wrote this little helper method to search the exception chain for a particular exception (either equals or super class). However, this seems like a solution to a common problem, so was thinking it must already exist somewhere, possibly in a library I have already imported. So, any ideas on if/where this might exist?

boolean exceptionSearch(Exception base, Class<?> search) {

    Throwable e = base;

    do {
        if (search.isAssignableFrom(e.getClass())) {
            return true;
        }
    } while ((e = e.getCause()) != null);

    return false;
}
