I did more testing, and I've found that the minimum value you can assign to
buffer-time without getting this exception depends on (at least) your jack
server's frames per period setting as well as its sample rate, both of which
can be determined with jack_get_buffer_size and jack_get_sample_rate,
respectively. 

For example, for a sample rate of 48000, the following combinations represent
the minimum buffer-times possible:

sample-rate: 48000
frames per period: [16   32   64    128   256   512    1024   2048]
min buffer-time:   [333  666  1333  2666  5333  10666  21333  42666]

or for 44100...

sample-rate: 44100
frames per period: [16   32   64    128    256   512    1024   2048]   
min buffer-time:   [362  725  1451  2902   5804  11609  23219  46439]
