Redirecting `stdin` for a run configuration on Windows hangs when buffered reader reaches EOF.

I have a simple Java CLI `my-cli` that reads lines from `stdin` until the end of the stream is reached:

```java
LineNumberReader reader = new LineNumberReader(new InputStreamReader(System.in));
String line;
while((line = reader.readLine()) != null) {
//TODO process the line
}
```

On Windows 10 from the command line, if I run `my-cli < test-input.txt`, then the input is rerouted and the program runs normally. The above loop ends when the end of the file (from which `stdin` is redirected) is reached.

I should be able to reproduce this behavior in Eclipse by assigning `stdin` to a file in the run configuration, in the setting window shown in an [answer](https://stackoverflow.com/a/31287752) to [Redirect stdin from a file in eclipse with run configuration](https://stackoverflow.com/questions/31234646/redirect-stdin-from-a-file-in-eclipse-with-run-configuration).

Unfortunately the Eclipse implementation seems to never detect the end of the file. Instead, when running the program inside the IDE, the call to `reader.readLine()` hangs when the end of the file is reached. It seems to hang in `java.io.FileInputStream.read(byte[] b, int off, int len)`, in the call to `return readBytes(b, off, len)` below:

```java
@Override
public int read(byte[] b, int off, int len) throws IOException {
long comp = Blocker.begin();
try {
return readBytes(b, off, len);
} finally {
Blocker.end(comp);
}
}
```

Here's the relevant part of the stack of the hung thread:

```

I'm using Java 24 on Eclipse 2025-06 (4.36.0).
