AEM 6.3 Content Fragment Model, Compilation Error on pathfield picker component

[pankajk49319]

While Setting up Content Fragment Model in AEM 6.3 and using the content reference Model, I am getting below Java exception in Error log.

I tried to follow following article,

Still getting the issue, has someone come across this issue, please share your thoughts.

It can be caused by :

• Missing OSGi bundles
• Stopped OSGi bundles
• Corrupt compiled jsp class files

Here is the KB article for this:- Compilation and classloading errors in custom application

Hi Kautak,

I already went through the article as I mentioned in question and verified the areas as per article but issue did not get resolved,

Can you please check this:

Go to crx/de

2) Comment out the @override annotations in children.java [1] on lines 91 and 127

in

3) Save

This could be a bug in 6.3. Please create a support ticket after trying out.

This Issue is resolved.

Root Cause: "Apache Sling Java Script Handler" was configured with Source & Target VM with 1.5 which was causing compilation of inline java file against Java 1.5 and throwing the Error. After updating values to auto compilation errors are not there.

Thank you,
