> need to fix a bug in TestBPOfferService#waitForBlockReceived that fails the
> trunk, e.g. in Build #1781.
> Details: in this test, the utility function waitForBlockReceived() has a bug:
> parameter mockNN is never used but hard-coded mockNN1 is used.
> This bug introduces undeterministic test failure when
> testBasicFunctionality() calls
> ret = waitForBlockReceived(FAKE_BLOCK, mockNN2);
> and the call finishes before the actual interaction with mockNN2 happens.
