*edits*

Think I finally see what happens - it's perhaps mainly a test issue. After we 
start solr for a test, we count on the things like the datadir being resolved 
*via a system property* - then we reset that *system property after starting 
solr* so we can use it for the next solr instance we start.

This can end up being a problem for reload. *We end up resolving again and the 
system property was not consistent* I think for this particular issue the best 
workaround is the one I mention above - explicitly pass the dataDir that was 
detected at core started rather than doing any re resolving?

You lose the ability to update the data dir with a core reload though...that 
could be considered an odd feature to support though?

Probably not worth it for a test issue - not sure how to fix the tests though...
