After upgrading it to spring boot version 1.5.9.RELEASE and spring cloud Edgware.RELEASE. It's started failing:

[kakawait]

Thank for reporting. I will try asap with latest 1.5.x

[kakawait]

@pandeymradul do you confirm that everything is working before upgrading Spring boot & spring cloud ?

[kakawait]

@pandeymradul I addition I upgrade Spring cloud to Edgard.RELEASE (Spring boot was already on 1.5.9) and sample still working.

Do you use sample or inside your own code/sample?

[mradulpandey]

No i tried your code, i will report the exact versions.

[kakawait]

Could you try on latest master branch I just pushed Spring cloud to Edgard.RELEASE

Moreover are using testing under docker ?

[mradulpandey]

I tried it with Edgware.SR1, every thing seems working fine. i am not able to reproduce it, i think we can close this issue.
