Hi Smac,
Please find the below references,

Screenshot:2

Screenshot:3

Screenshot:4

Issue in detail:
1) In screenshot:1 line no:91, I'm trying to get the languageManager from config.
2) In screenshot:2 line no:55 I'm getting properties from serviceFactory. serviceFactory is nothing but DefaultHybrisfactory.
3) In screenshot:3 DefaultHybriFactory extends AbstarctJcrCommerceServiceFactory where the languageManager has been referred.
4) In screenshot:4 If you see the AbstarctJcrCommerceServiceFactory predefined class, it has the LanguageManager Reference, but here everything is in felix annotation.
5) Finally when I get the languageManager from AbstarctJcrCommerceServiceFactory I'm getting null value.(I'm using OSGI annotations)
6) The same code is working fine in 6.1 with felix annotations(felix annotations used in my code not OSGI)
I'm suspecting that, Since I have converted all the felix annotations to OSGI in my code but the predefined class (AbstarctJcrCommerceServiceFactory) is still having felix annotations. that's why I'm getting null value?
Thanks,
Vijay
