jdbc-jtds is fine to build on Java 6 thus not sure why it's filtered also an *all:release* task is quite dangerous - remove it
this will allow to raise the LoadError on non Java 7 with jTDS 1.3
change generic autoload controll option name to jdbc.driver.autoload (provides backward-compatibility with AR-JDBC < 1.2.3 as well as other libraries) + provide a specific autoload option as well ...
- Update the version handling. Rather than string mangling, use simpler DRIVER_VERSION and VERSION constants. - Invert the (never released) autoload property behavior. Instead of requiring a property to opt in to the new behavior, require a property (arjdbc.force.autoload) to retain the old behavior.
bellow using `remove_const(:PostgreSQLAdapter)`
if the AR::Result is set up correctly also add explain test with binds
make MySQL explain a re-usable module as well (just in case - someone'd like to reuse explain support into another adapter)
