jdbc-postgres jar never gets loaded from do_postgres in JRuby

[ghost]

As the title says, the jar from jdbc-postgres is never loaded in do_postgres.

The file is loaded through require, but the subsequent java_import will always fail, because Jdbc::Postgres::load_driver never gets called. jdbc-postgres provides the module with the method to load it, but it is not used. Thus using do_postgres under JRuby will cause errors about not finding org.postgres.Driver from the java_import.

A simple case of:

DataMapper.setup :default, {
:adapter => 'postgres',
:host => 'localhost',
:database => 'GenesisDevelopment',
:user => 'postgres',
}

under JRuby will cause this issue.

I can not reproduce this error with do_postgres version 0.10.11

could you please provide jruby version, do_postgres version ? maybe also dm-postgres-adapter version ?

This is apparently something that changed with recent jdbc-* gems which I didn't know about. This was fixed in e120100
