Shai Erera updated SOLR-7408:
-----------------------------
Attachment: SOLR-7408.patch
* Remove ZkController.watchZkDir
* Remove code which cleaned the map in .unregister()
* Ensures SolrCore is closed on any errors
* Simplifies SolrCore ctor a bit by extracting logic to separate methods. More
can be done I'm sure, by breaking out this class into several auxiliary
classes, but not in the context of this issue.
Tests pass.
> Let SolrCore be the only thing which registers/unregisters a config directory
> listener

> As reported here: http://markmail.org/message/ynkm2axkdprppgef, there is a
> race condition which results in an exception when creating multiple
> collections over the same config set. I was able to reproduce it in a test,
> although I am only able to reproduce if I put break points and manually
> simulate the problematic context switches.
