A DESCRIPTION OF THE PROBLEM :
In the JavaDoc for the InputStream.read(byte[] b) method, in the "returns" section, the word "is" is used where it should be the word "if":

This:
"...or -1 is there is no more data..."
should be:
"...or -1 if there is no more data ..."



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Returns:
    the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.
ACTUAL -
Returns:
    the total number of bytes read into the buffer, or -1 is there is no more data because the end of the stream has been reached.
