JdbcConnection Java cleanup - avoid & remove some of the deprecated methods
save a List use a RubyArray directly
cache some column/table name (Ruby) string + mapTables needs to be re-thinked
hand-crafted "new" internal (JDBC) connection management ... shall get lazy later 4 jndi
avoid throwing checked exception from JRuby method + deprecate + runtime.getTrue
cache `config[:connection_alive_sql]` and do not check if it's a select (user knows)
cache the jndi flag for the connection + renamed lazyConnection field
missing JRuby annotation
move adapter test methods into their own place
JNDI's lazy by default + no active? connection checking when using a data-source
no longer default to `config[:retry_count] ||= 1`
use assert_raise_kind_of for less test surprises on AR < 4.0
