One pattern is for example when reading from a stream and closing it is highly unlikely to generate an exception, then instead of the try block in

InputStream in = ...;
while(someCondition) {
    int b = in.read();
    // process b
}
try {
    in.close();
} catch (IOException ignored) {
}

one could simply write

in.closeUnchecked();

and avoid the boilerplate imposed by the checked exception. This sort of code can be found in many places in the tests in `<OpenJDK>/test/jdk`.
