The puzzle is that it requires t.read() to succeed.

When I insert a check for bytes type in all the places it seems necessary in my code, I pass the first two conditions, but since t.read() also raises TypeError, the overall test fails. Is reading the stream with read() intended to succeed? Why is this desired?

And alternative option is to change C implementation of TextIOWrapper.read() to raise an exception in this case. However I worry that it can break backward compatibility. Are there other tests (in other test files) which fail with a new Jython TextIOWrapper?
