This is happening intermittently since the order in which components are
resolved in OSGi varies. AFAIR this issue was there in Kernel 5.1.0, but
this was fixed in the startup order resolver to catch this issue (if the
component such as number of expected and actual being registered vary [2]).
In order to identify this issue, you need to narrow down which component is
causing this issue.

For C5, the maven should be 3.3.x and JDK should be 1.8.x (Oracle /
OpenJDK). This is mentioned in the [1]. We need to added in the Github
Readme as well. If your components are compiled using maven 3.0.5 then it
is not compatible with C5.

2017-02-19 Thread Harsha Thirimanna

What do you mean by properly ? Is that possible to happen these issues
intermittently if it is not defined properly ? 

Yes I am using maven 3.0.5 and you are saying still it can be happened
intermittently because of this ? Because of some others using same maven
but never seen this issue.

And I have seen another issue that OSGi services not register
intermittently. Is that the same issue as you suggested ?

This issue happens when you have not defined your components properly. In
C5, we have introduced startup order resolver. This is introduced when a
components need to wait till other components are initialized (refer [1]).

Btw I have noticed that for C5 components some are using Java 1.8 and maven
3.0.5. Please note for C5, you need to have maven 3.3.x.

Hi all,

We have also witnessed this intermittently in C5 APIM server recently.
Could not found any exact steps to reproduce.

Thanks!
