Files.readAllLines() throws an exception every time.

I can't figure out why an exception is being thrown by this line of code, it used to work in an earlier version but now it just doesn't. Am I somehow using it wrong?

            List<String> lines;
            functions = functionsDir.listFiles();
            for (File f : functions) {
                fileCount++;
                lines = Files.readAllLines(f.toPath(), StandardCharsets.UTF_8); //PROBLEM LINE
                lineCount += lines.size();
            }

            List<String> lines;
            functions = functionsDir.listFiles();
            for (File f : functions) {
                fileCount++;
                lines = Files.readAllLines(f.toPath(), StandardCharsets.UTF_8); //PROBLEM LINE
                lineCount += lines.size();
            }

Here's how it looks in my code

DevinOP•10mo ago

and that's the stacktrace

DevinOP•10mo ago

For additional context, I am running it from the right place as well

DevinOP•10mo ago

I just don't understand where this comes from? What does it mean "malformed input"?

tldr java cant really convert the bytes in the file back to text with the encoding you specified what’s in the file?

Kyo-chan•10mo ago

It's weird though, a badly encoded file shouldn't throw an exception, it should produce error characters

DevinOP•10mo ago

Well, what's odd about this is that I actually don't care what the text is in the file I'm not sure what file it's on, I'll try adding that code to my catch block. They're all .mcfunction files though, none of them should contain characters you wouldn't find in a minecraft command actually, at least one of them has the ☭ character in it for coin redistribution could that be it? oh I see I can't refer to F in my catch block because I think the scope is too wide?

right that makes sense I'll try moving code around

DevinOP•10mo ago

even the file with that weird char is UTF-8 tho

It's literally just a helper class so I don't need to remember the escape sequences
