[Bug classpath/22895] New: Java NIO: ReadableByteChannel.read() tries to read to much data

[pinskia at gcc dot gnu dot org]

The specification says the read(ByteBuffer bb) method should not read more than 
bb.remaining(). However at least for our SocketChannel implementation this is 
not provided.



A testcase may be written this way



// A channel that is know to have data in it

ReadableByteChannel rbc = ...



// some ByteBuffer (may be direct or not)

ByteBuffer bb = ...



// fills it to the max

while(bb.hasRemaining()) {

    bb.put((byte) 12);

}



int read = -1;

boolean exceptionThrown = false;



try {

  read = rbc.read(bb);

} catch(Exception e) {

  exceptionThrown = true;

}



harness.check(read, 0);

harness.check(exceptionThrown, false);



Then we just need to create all kinds of ReadableByteChannel implmentations and 
run this against this framework.

I work on this.
