Marios Andreou commented on DTACLOUD-430:
-----------------------------------------

OK  <breathe> :

* reproducible on 1.8.7 

* GET /cimi/network_configurations actually works now. but.

* GET /cimi/cloudEntryPoint explodes

* brute force bisection lead me to the offending commit # 
1773ecc930216df0baa588a42ead7c7e94e76986 

* A number of files are edited in this commit. I narrowed it down to  
server/lib/cimi/collections/volume_templates.rb - i.e. the collection 
definition for volume_templates. I mean, by 'git reset' and 'git checkout' the 
changes in this file, GET /cimi/cloudEntryPoint works again.

* you can actually pull latest master - and delete 
server/lib/cimi/collections/volume_templates.rb - to make everything work 
again. i can't see what's special about this definition.

* still under investigation

* The actual stack trace reads:
