Remove tzinfo dependency from Action Pack
There's no need to do this

AS does the following inside Time.find_zone! ...
`ActiveSupport::TimeZone[time_zone] || TZInfo::Timezone.get(time_zone)`
and given that the test is stubbing AS::TZ[] we don't need the removed
code.

do what the superclass does in the case that objects do not match
ActiveRecord::Base#<=> has been removed.  Primary keys may not be in order,
or even be numbers, so sorting by id doesn't make sense.  Please use `sort_by`
and specify the attribute you wish to sort with.  For example, change:

  Post.all.to_a.sort

to:

  Post.all.to_a.sort_by(&:id)
support objects with blank string primary keys
remove unused variable
NullSessionHash#destroy should be a no-op

Previously it was raising a NilException

Calling reset_session inside of a controller with a NullSessionHash raises a nil exception.

Bust the template digest cache key when details are changed

Since the lookup details will influence which template is resolved, they
need to be included in the cache key -- otherwise two different
templates may erroneously share the same digest value.

Fix incorrect assert_redirected_to failure message

In some instances, `assert_redirected_to` assertion was returning an
incorrect and misleading failure message when the assertion failed.
This was due to a disconnect in how the assertion computes the redirect
string for the failure message and how `redirect_to` computes the
string that is actually used for redirection.

I made the `_compute_redirect_to_loaction` method used by `redirect_to`
public and call that from the method `assert_redirect_to` uses to
calculate the URL.

The reveals a new test failure due to the regex used by
`_compute_redirect_to_location` allow `_` in the URL scheme.
Fix regex used to find URI schemes in redirect_to

The previous regex was allowing `_` in the URI scheme, which is not
allowed by RFC 3986. This change brings the regex in line with the RFC.

Run Tests against JRuby master

Many of the failing tests in rails test suite fail because of missing encoding support, example #11739


And according to recent announcement, lot of encoding issues have been fixed in current master.  http://ruby.11.x6.nabble.com/Big-encoding-patches-landed-on-master-td4993719.html


So lets test against JRuby master & incase there are still bugs. it would be easier to report them to JRuby.
