Identical 'catch' branches in 'try' statement

Reports identical catch sections in a single try statement.

Collapsing such sections into one multi-catch block reduces code duplication and prevents the situations when one catch section is updated, and another one is not.

Example:

try {
    doSmth();
}
catch (IOException e) {
    LOG.error(e);
}
catch (URISyntaxException e) {
    LOG.error(e);
}

A quick-fix is available to make the code more compact:

try {
    doSmth();
}
catch (IOException | URISyntaxException e) {
    LOG.error(e);
}

This inspection only reports if the language level of the project or module is 7 or higher.
