and this has fixed my problem
I am getting same issue when migrating from AEM 6.1 to AEM 6.3. We did an inplace upgrade. How do I find obsolete bundles in my instance. I dont have above bundles mentioned by Stanleyor.
Any thoughts what I need to check?
Thanks in advance!
The issue was fixed in https://issues.apache.org/jira/browse/SLING-7044
Summary of the issue :
If a taglib in a bundle references a tag implemented as a script (located in /META-INF/tags) this script is not found as it is not searched within the bundle containing the tld - it's rather used as a resource on the classpath.
