Infinite Loop in KeepAliveStream

An infinite loop has been observed in jdk/src/share/classes/sun/net/www/http/KeepAliveStream.java

 85: if (nskip <= available()) {
 86: long n = 0;
 87: while (n < nskip) {
 88: nskip = nskip - n;
 89: n = skip(nskip);
 90: }

If this stream is asynchronously closed (or perhaps, read, or skipped), then skip will always return 0 (see MeteredStream)

    public synchronized long skip(long n) throws IOException {

        // REMIND: what does skip do on EOF????
        if (closed) {
            return 0;
        }

and you can clearly see an infinite loop.

Here's an infinite loop stack trace snippet (line numbers from openjdk6 sources)
