Bug description ---> Method read() of class java.io.ImputStreamReader
reads characters from stream containing invalid bytes for selected
encoding instead of throwing exception.

How to reproduce:
====================
Compile and execute the following program.
It constructs InputStreamReader with UTF8 encoding and tries to
read invalid (in UTF8 encoding) bytes. Read method should throw
exception.

import java.io.*;

class test {
    public static void main(String args[]) throws Exception{
        byte[] bytes = { (byte)230, 10, (byte)128 };
        InputStreamReader isr = new InputStreamReader(new ByteArrayInputStream(bytes), "UTF8");
        try {
            isr.read();
        } catch (IOException ioe) {
System.err.println(ioe);
return;
        }
System.out.println("Exception not thrown");
    }
}

Test output:
=============
api/java_io/Reader/index.html#read:
    Read3Test0010: Failed. read should have thrown IOException
api/java_io/InputStreamReader/index.html#read1:
    Read2Test0007: Failed. IOException not thrown as expected.
api/java_io/InputStreamReader/index.html#read:
    Read1Test0012: Failed. read should have thrown IOException
