Ok, thanks. I see two potential problems in your code:

What's this "chainFileSeed"? If you're trying to shortcut the
block(header) downloading, I suggest using the CheckpointManager class
instead. See the WalletAppKit.java code and
https://bitcoinj.github.io/speeding-up-chain-sync

Why don't you use a fixed date here, rather than a relative date? The
key/address you're using was likely created at a fixed date; if current
date minus one month lies before that your test will fail.
That said, it is possible that createBasic() is buggy. The case of a
wallet without keychains (only imported keys) has received less testing.
Can you share the public key part of your key, so that I can run the
exact same test? Or, if your key is worthless, you can just as well
share the private key.
