[Bug libgcj/21270] New: BufferedReader.read( char[], int, int ) returns less than expected number of read chars

[mnefedov at rogers dot com]

When 8K of data is requested gcj returns only 2K (Sun's VM returns full 8K).

example code:

import java.io.*;

public class BufferedReaderReadTest {
	public static void main( String [] args ) throws Exception {

		char [] b = new char[ 8 * 1024 ];

		BufferedReader in = new BufferedReader( new FileReader( args
[0] ), 8 * 1024 );

		System.out.println( "read() = " + in.read( b, 0, b.length ) );

		in.close();
	}
}

           Summary: BufferedReader.read( char[], int, int ) returns less
                    than expected number of read chars

Note BufferedReader does not need to read in the full buffer, it actually is a non blocking reader:
>From <http://java.sun.com/j2se/1.4.2/docs/api/java/io/
BufferedReader.html#read(char[],%20int,%20int)>
The ready method of the underlying stream  returns false, indicating that further input requests  would 
block.

so I don't know if this is a real bug or not.
