If I change one of the two test classes that triggers this problem to create a single database for the entire test class, the problem changes from a too large buffer being read (which causes the hang) to an error

Unsupported or unexpected operation code 16777216 in processOperation [SQLState:08000, ISC error code:337248276]

This error means that Jaybird received a response packet with an operation code of 16777216 instead of a valid operation code (op_response (9), op_fetch_response (66) or op_sql_response (78)).

It looks like the previous packet was a little smaller than you expected because 16777216 is "01 00 00 00" which may be a valid piece of status vector.
