[rabbitmq-discuss] JSON dependency for codegen - suggestion

Replying to myself as usual ;)

Nope..the codegen project is appended to the python path and dropping the
json.py in there works just fine for both the broker and the java client
projects...just not with python 2.6 on Windows, which is of course what I
tried :(

C:\home\holger\Projects\rabbitmq-java-client\build.xml:55: Generation of
AMQP.java failed with message:
Traceback (most recent call last):
  File "codegen.py", line 393, in <module>
    do_main(generateJavaApi, generateJavaImpl)
  File "../rabbitmq-codegen\amqp_codegen.py", line 166, in do_main

  File "../rabbitmq-codegen\amqp_codegen.py", line 48, in __init__
    self.spec = json.read(file(filename).read())
AttributeError: 'module' object has no attribute 'read'

Any python wiz who knows what changed from 2.5 to 2.6 that could cause
such breakage?

That would still be nice, provided we can figure out how to make it work
with python 2.6.
