Issue in sightly component after upgrade from 6.0 to 6.2

[diptinarang]

We are experiencing issues in sightly components, wherever we have referenced Java classes like this - "global.Packages.com.xyz.wcm.utils.ABCClient"

Exception:

GET /content/xyz/ab/new.html HTTP/1.1] org.apache.sling.engine.impl.SlingRequestProcessorImpl service: Uncaught SlingException

java.lang.NoClassDefFoundError: Could not initialize class com.xyz.wcm.utils.ABCClient

I couldn't find any deprecations related to this in following documents:

https://docs.adobe.com/docs/en/aem/6-2/develop/ref/javadoc/deprecated-list.html#package

https://docs.adobe.com/docs/en/aem/6-2/release-notes/deprecated-removed-features.html

https://docs.adobe.com/docs/en/aem/6-2/develop/ref/diff-previous/changes.html

Also the fix mentioned here, didn't work:

Hi, Dipti.

To which classes/packages are you referring to? Are they part of the AEM core or are they custom/3rd-party?

What is the status of the bundle that export those packages/classes? Is it active?

Regards,

Daniel.

[diptinarang]

Thanks for reverting Daniel. These are our custom classes and they are working fine when referenced in JSP or other Java code.

I checked the status of bundle which export this class and it is active.

Thanks, Dipti

Hi,

what is this class "ABCClient" specifically? Is it a WCMUse Pojo, a SlingModel? Or just a random class which is referenced from your Javascript (?) models?

It's a random class.

Thanks, Dipti

Hi Dipti,

does this happen only for some classes or for all? In any way I recommend you to open a ticket at Adobe support.

[diptinarang]

It is happening for all classes.

Can you also try to test this on a vanilla 6.2 instance?

[diptinarang · Accepted solution]

The issue is resolved by granting admin like rights to system user. But the error message thrown was bit misleading and that's why I suspected that issue is in sightly.

Thanks everyone for your valuable inputs.

You mean on the OS?, since 6.2/6.1 the compiled files are saved on the OS.
