[lucene-solr] branch reference_impl_dev updated (27ca697 -> bff0f22)

This is an automated email from the ASF dual-hosted git repository.

markrmiller pushed a change to branch reference_impl_dev
in repository https://gitbox.apache.org/repos/asf/lucene-solr.git.


    from 27ca697  @1396 Finish not retrying on session expiration in some key spots.
     new 158fe23  @1397 More work on Nightly run, pass jvm max file setting for osx, notifyAll was used instead of signalAll.
     new bff0f22  @1398 More on the Nightly test run, bring the UpdateLog into spec, maybe look at object reuse again later.

The 2 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails.  The revisions
listed as "add" were already present in the repository and have only
been added to this reference.
