Subject Re: NPE at application deployment
Date Sun, 25 Jan 2015 03:13:07 GMT
Yes there seems to be a functional issue here:
https://github.com/apache/stratos/commit/c41e66b2678a463c4ccdfdf01298daf723e0eb2f?diff=unified

Dependency order property is set twice to the application, second call
overwrites the startup orders set at the beginning.
