The documentation for java.io.ByteArrayOutputStream constructor
does not mention NegativeArraySizeException. This exception
is thrown when negative parameter is passed to the constructor.

_______ Specification for ByteArrayOutputStream(int) _______
22.18.4 public ByteArrayOutputStream(int size)

This constructor initializes a newly created ByteArrayOutputStream so that
its internal buffer array has length size. This matters only for reasons
of efficiency; the buffer array is replaced by a larger one whenever necessary
to accommodate additional bytes written to the stream.

_______________________ Example ______________________________________
import java.io.*;

public class bug_tests {

 public static void main( String argv[] ) {
   
  try {
 ByteArrayOutputStream y1 = new ByteArrayOutputStream(-1); // Create new object
  } catch (NegativeArraySizeException e) // Catch the exception
    { System.out.println(" It is expected but non-documented exception:"+e);
    }

    catch (Exception e)
    {
     System.out.println(" Unexpected exception:"+e);
    }
  }
}
