Affects PMD Version: 7.7.0
Rule: UnusedPrivateMethod
Description:
Code Sample demonstrating the issue:
private String foo(final Object foo, final String bar) {
final String abc = Optional.ofNullable(foo.toString()).map(Foo::getNormalizedAddress).orElse(null);
return abc;
}
private static String getNormalizedAddress(final String encoded) {
try (var objectInputStream = new ObjectInputStream(new ByteArrayInputStream(Base64.getDecoder().decode(encoded)))) {
final var inetSocketAddress = (InetSocketAddress) objectInputStream.readObject();
return inetSocketAddress.toString().substring(1);
} catch (IOException | ClassNotFoundException | IllegalArgumentException e) {
return null;
}
}
Expected outcome:
PMD reports a violation at line ..., but that's wrong. That's a false positive.
The method is clearly being used
