Uhh, I don't know Java6 very well (yet), as at work we're forced to
Java5 (and sometimes even 1.4) by the compatibility matrix of some big
products we need to integrate with…
Another option could be simply to return "0.51-native" or "0.51-pure"
from conn.getMetaData().getDriverVersion(), which right now is only
returning "1" actually.
Quick hack:
