I asked this question about a week ago on the Firebird-Java list and the
resounding reply was yes!

I've since run several tests that confirm the thread-safeness of the
embedded server.

I am, however, running into a problem with Firebird2 when I create a new
connection in a thread (at least using the Jaybird JDBC driver). This
may not apply to you though.

I you want more details, take a look at the discussion archive for the
Firebird-Java list.
