In Jython 2.5.2 (I didn't see 2.5.2 in the version list) os.read() returns an object of type unicode, but should return an object of type str in Python 2.x's.
This is inconsistent with CPython 2.x and PyPy 1.4.1, both of which return str.
Because CPython 3.x's os.read() returns bytes (which are similar to 2.x str's), use of os.read() is perhaps becoming important for systems programming, where os.read() gives nice binary blobs in both 2.x and 3.x, without imposing any encoding assumptions on the data being read.

This is great. How soon might I hope for a 2.5.3 that would include it?
Or should I just figure out how to build a trunk?

2.5.2 was released fairly recently, and now we're focused on 2.6 work, so I don't expect a 2.5.3 any time soon.
I did apply this change to the 2.5 branch however, if you want to build your own release from there.

Something seems not-quite-right:
$ /usr/local/jython-2.5.2-r7288/bin/jython
cmd started 2011 Fri Apr 22 08:20:53 PM
*sys-package-mgr*: can't create package cache dir,
'/usr/local/jython-2.5.2-r7288/cachedir/packages'
Jython 2.5.2 (Release_2_5maint:7288, Apr 22 2011, 19:40:21)

>>> import os
>>> filedes = os.open('/etc/protocols', os.O_RDONLY)
>>> data = filedes.read(100)
>>> data
java.nio.HeapByteBuffer[pos=0 lim=100 cap=100]
>>> type(data)
<type 'java.nio.HeapByteBuffer'>
>>> data[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'java.nio.HeapByteBuffer' object is unsubscriptable
>>> os.close(filedes)

data should be a str with around 100 characters in it, or at least something
that quacks like a str.
Thoughts?

You've mistakenly called <fileno>.read(100) instead of os.read(fileno, 100)
Our file descriptors are weird =]
