FULL PRODUCT VERSION :
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0)
Java HotSpot(TM) Client VM (build 1.3.0, mixed mode)

FULL OPERATING SYSTEM VERSION : Any


A DESCRIPTION OF THE PROBLEM :
ByteArrayOutputStream does not override write(byte[])
method of OutputStream. write(byte[]) of
OutputStream throws IOException

As a result one always
has to do something like this:

ByteArrayOutputStream b;

try {
   b.write(buffer);
} catch (IOException e) {
   // never happens
}

Otherwise compiler will complain.


Note that I can avoid this by doing

   b.write(buffer, 0, buffer.length);

Since this method is implemented in ByteArrayOutputStream

This is very annoying.




STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
add the following in you program:


ByteArrayOutputStream bos = new ByteArrayOutputStream();


bos.write(new byte[1]);

This will not compile and you will have to
wrap it into a try block which is not necessary since
this method actually never throws IOException


try {
     bos.write(new byte[1]);
} catch (IOException e){
    // never happens
}






EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected - method should not need a try block around it
Actual - try block needed, otherwise this will not compile

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Compiler: IOException musr be caught or declared thrown.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
include java.io.*;

// this will not compile
public class Test {
   public static void main(String[] x) {
        new ByteArrayOutputStream.write(new byte[1]);
   }
}


---------- END SOURCE ----------

CUSTOMER WORKAROUND :
Always include unnecessaty try/catch block -
very awkward
