undefined method `database_product' for nil:NilClass

Hey!

Testing out jruby on an existing MRI app (postgresql).

jruby 9.4.9.0 (3.1.4) 2024-11-04 547c6b150e OpenJDK 64-Bit Server VM 17.0.2+8 on 17.0.2+8 +jit [x86_64-darwin]

Localhost launches fine, but when opening it in the browser it seems that something is going wrong with the DB connection:

NoMethodError (undefined method `database_product' for nil:NilClass):

activerecord-jdbc-adapter-70.2 (java) lib/arjdbc/postgresql/adapter.rb:56:in redshift?' activerecord-jdbc-adapter-70.2 (java) lib/arjdbc/postgresql/adapter.rb:509:inclient_min_messages=' activerecord-jdbc-adapter-70.2 (java) lib/arjdbc/postgresql/adapter.rb:76:in configure_connection' arjdbc/jdbc/RubyJdbcConnection.java:596:inconfigure_connection' activerecord-jdbc-adapter-70.2 (java) lib/arjdbc/abstract/core.rb:25:in initialize' activerecord-jdbc-adapter-70.2 (java) lib/arjdbc/abstract/statement_cache.rb:23:ininitialize' activerecord-jdbc-adapter-70.2 (java) lib/arjdbc/postgresql/adapter.rb:769:in initialize' org/jruby/RubyClass.java:949:innew'

Extracted source around line #56:

  if ( redshift = config[:redshift] ).nil?        
        redshift = !! (@connection.database_product || '').index('Redshift')       
  end
  redshift

end

Standard database.yml, works well on MRI.

Thanks for the report! Is your Rails app also Rails 7.0? The latest ARJDBC adapters currently released are for 7.0 and probably won't work on a Rails 7.1 or higher app.

Thank you. I tried downgrading to Rails 7.0 and using the 70.0 version of the adapter and the issue was solved.

@tykonu okay, thanks for the update. I'm going to close this, since we already have plenty of other issues tracking the rails 7.1 compatibility work.
