Where can i find a snapshot of current 2.2 version?

I found one at http://jaybirdwiki.firebirdsql.org, but "isValid" is not working there...

if (c.isValid(100))

Exception in thread "main" java.lang.AbstractMethodError: org.firebirdsql.jdbc.FBConnection.isValid(I)Z
at Teste05.main(Teste05.java:55)

Regards,

Fabiano
