Hi all, I have a follow up question from this thread I started some time ago. Since then, I have been trying out the following property and value: org.osgi.framework.storage.clean=onFirstInit
Which appears to work well, and removes extraneous directories and files from my bundle cache directory shortly after startup. Note that it doesn't matter whether these directories and files were originally created by Felix. If they are in the bundle cache directory, they are removed. I also tried calling refreshPackages(null) on the PackageAdmin service object at runtime. When I do this, the message "FrameworkEvent PACKAGES REFRESHED" is logged. It may be doing something, but the behavior is not the same as with the org.osgi.framework.storage.clean property. Extraneous directories and files are not removed. I was expecting the behavior to be the same between the two approaches. Can somebody please explain the distinction? Is there runtime access to the behavior that org.osgi.framework.storage.clean exhibits? In case there is some confusion, I am not worrying about precisely the same problem as in the original thread, but instead solving a problem where occasionally old bundle caches are present for bundles that are no longer in use.
