That was a useful read, thank you. It leaves me with just one question:
what triggers a framework refresh? (other than a startup/shutdown)
Explicitly calling PackageAdmin.refreshPackages(), which is done by
getting the PackageAdmin service or the Felix shell provides a "refresh"
command.

From this point onward I will make a note of whether I ever see multiple
version directories at a point in time when I should not.
Thanks!

Hi all,
I have a question about the "versionX.X" directories inside the Felix
bundle cache. I am using Felix 2.0.0, and I often see something like
the
following in my bundle cache directory:
ls -l
bundle0
bundle1
...
cd bundle0
ls -l
version0.1
version0.0
bundle.location
bundle.startlevel
bundle.lastmodified
bundle.id
bundle.state
ls -l version0.0
bundle.jar
ls -l version0.1
bundle.jar
What I mean to be pointing out here are the two "bundle.jar" files in
two
different "versionX.X" directories in the cache area for one bundle.
What
is the reason that I might get more than one of these? How can I avoid
that? I have limited space on the device our product runs on, and even
the size of these jar files can make a difference.
Note that I am using the autodeploy feature with actions
"install,start,update". Sometimes the original bundle jars in the
autodeploy directory change from one run to the next.
You might want to read:
http://felix.apache.org/site/apache-felix-framework-bundle-cache.html
Typically, what you are seeing is the result of doing updates. However,
typically the extra JAR files should be deleted after a refresh.
Starting with "install,start,update" causes the update, but generally
i'd assume you'd autorefresh during startup so you wouldn't see
additional JAR files. Perhaps you could verify that refreshing is
deleting the JAR files. If so, you could verify that they are
automatically getting deleted on startup.
By and large, after your framework starts I'd expect there to be no
additional JAR files and after it stops I'd expect there to be no
additional JAR files too. At run time, it just depends on whether you've
updated and not refreshed yet.

Thanks,
Matt
