I was just running the Jaybird tests against Firebird-4.0.0.1227-0_x64
(Windows 10). It has been a while since I tested with Firebird 4, so I
don't know when this problem was introduced.
When running the test
org.firebirdsql.gds.TestReconnectTransaction.testReconnectTransaction, I
get an error when trying to rollback a limbo transaction:
Likely a related issue, another test
(org.firebirdsql.gds.ng.wire.version10.TestV10Transaction.testBasicPrepareAndRollback)
gets stuck.
This test creates a connection, starts a transaction (read committed
record version wait), inserts a value into a table, prepares the
transaction (to be committed later in the test).
Then in a separate connection + transaction (also read committed record
version wait), the test attempts to select from the table. This
connection is stuck fetching rows (even when setting ReadConsistency = 0
in firebird.conf).
This works fine in Firebird 3 and earlier.
With setting ReadConsistency = 0 in firebird.conf this is logged (after
killing the test):

Interestingly after this test, Firebird has no problem shutting down
with setting ReadConsistency = 0, but hangs with setting ReadConsistency
= 1.
