Yes. You can execute statement "commit retaining" like any other statement. Execute "commit" work for Firebird API and didn't work for Jaybird.
Example(it's work):
....
PreparedStatement commitRetaining = connection.prepareStatement("commit retaining");

.....
commitRetaining.executeUpdate();// Call commit retaining

....
