RFR: 8189366: SocketInputStream.available() should check for eof

[Bernd Eckenfels]

What is currently returned at the end of a stream? This looks like a dangerous thing to do, if a existing implementation only read when something is available it might never detect that it reached EOF.

Hi All,

Please review the simple change below.

Webrev   : http://cr.openjdk.java.net/~vtewari/8189366/webrev0.0/index.html

BugId      : https://bugs.openjdk.java.net/browse/JDK-8189366


Currently SocketInputStream.available() does not check for "eof" and
simply delegate to the impl even when "eof" reached. I put a check  to
return 0 if "eof" is already reached.

Thanks,

Vyom
