The arrays have some history behind - it was done for request of one big
company that needed to store data from different sensors in their
experiments somewhere in 80s. The arrays themselves are simple BLOBs
with some internal structure. Support for arrays in Firebird is quite
rudimentary - you can access the item in arrays via its index and that's
it. The API calls are even worser - each access to an item might require
additional roundtrip to the server.

In Jaybird support for arrays require some research - the wire protocol
for the calls to access array elements is not implemented in Java (the
JNI-based stuff can be implemented more easily). However considering the
low popularity of arrays in FB, support for them in Jaybird is also low
prio for me. However, let's keep the request there, maybe there will be
some volunteer to add this code.
