Attempting to call read([n]) on a Java InputStream that has been turned
into a PyObject will crash with "read(): 1st arg can't be coerced to
byte[]". The PyObject conversion should create a read(int) method on the
InputStream to create and return a length-n byte[].

RFE for enhanced Java integration, so deferring until 2.5.1

It sounds like you're just not using an InputStream correctly. There's 
only read(), read(byte[]) and read(byte[], int, int). You can create a 
byte[] with the array module to use the latter 2, e.g.:

>>> fp = open('/tmp/foo', 'w+')
>>> fp.write('Hello World')
>>> from import FileInputStream    
>>> import array
>>> fis = FileInputStream('/tmp/foo')
>>> chr(
>>> buf = array.array('b', [0] * 10)
>>> buf
array('b', [101, 108, 108, 111, 32, 87, 111, 114, 108, 100])
>>> buf.tostring()
'ello World'
