Shawn Heisey commented on SOLR-13672:
-------------------------------------
I think I would call this a bug in ZK. But since getting a fix from them could
take a long time, we need to tackle this in Solr.
There are probably two ways to handle this. 1) Look for the = separator, and
if not found, use the : separator. 2) Treat the conf output as a .properties
file and let Java parse it for us.
I'm attaching a patch that takes the first approach.
