-------------------------------------
Summary: Exception handling while clearing OSGiServiceReferences
Key: SLING-11132
URL: https://issues.apache.org/jira/browse/SLING-11132
Project: Sling
Issue Type: Improvement
Components: Sling Models
Affects Versions: Models Implementation 1.5.0
Reporter: Sagar Miglani
*"Sling Models OSGi Service Disposal Job"* to clean the OSGi service references
does not do any error handling.
If a ungetting of a reference [0] is failed due to some exception (like
java.lang.IllegalStateException: Invalid BundleContext) no more references
present in queue are cleaned up in same job trigger. The next reference in
queue will be tried after 30 seconds (default) in next job trigger. Therefore,
it may take an hour to clean up 120 references with an error.
To reproduce this:
# Create a model consisting of OSGiService Injection
# Use this model in a page
# Open the created page and refresh it couple of time (10-15)
# Restart the bundle with model created in step 1
# One may see the following exceptions in the logs (after every ~30 seconds to
clear up the OSGi service references)
