Hi,
This worries me a bit, since we have a few bundles with embedded jar
files on the class path...
Will look into this when it becomes an issue for us.
I do think someone could create a script for this fairly easily. The old
cache format is typically like this:
felix-cache/
bundleN/
versionX.0/
bundle.jar
embedded/
embedded.jar
bundle.../
The only thing that needs to happen is the above "embedded/" directory
needs to literally be renamed to "bundle.jar-embedded/". The
"bundle.jar" name is a constant, so that won't change. We would end up with:
felix-cache/
bundleN/
versionX.0/
bundle.jar
bundle.jar-embedded/
embedded.jar
bundle.../
So if you have a cache with lots of embedded JAR files, at least we will
have a good test case to verify if renaming the embedded directory
works. :-)

Thanks for the clarification.

Hi,
What does this mean for my framework bundle cache created with a current
framework when upgrading to framework 2 ? Will the bundle cache be
migrated or just be used as is ?
If you have an existing cache you want to use with Felix 2.0, it will
need to be migrated if and only if your bundles have embedded JAR
files on their bundle class path.
To be more clear, *you* will need to migrate it by renaming the
directories to which embedded JARs are extracted.

Remove legacy bundle cache support when extracting embedded JAR files
---------------------------------------------------------------------
Key: FELIX-1300
URL: https://issues.apache.org/jira/browse/FELIX-1300
Project: Felix
Issue Type: Improvement
Components: Framework
Affects Versions: felix-1.8.1
Reporter: Richard S. Hall
Assignee: Richard S. Hall
Priority: Minor
Fix For: felix-2.0.0
A while ago we modified IContent so we could use that interface to
extract JAR files, which was necessary for fragment support where we
needed to be able to access embedded content to construct the host
class path. The approach is actually more powerful than what is
necessary, since we allow JAR files to be extracted from embedded
JAR files and JAR files embedded in the embedded JAR files to be
extracted and so. As a result of this, you can end up with situation
where embedded JAR files in different embedded JAR files may have
the same name, so to avoid name clashes, we extract embedded JAR
files into a directory named after the bundle. This was problematic
at the top-level, since it would not be backwards compatible with
existing caches. As a result, we special case the top-level and just
use the name "embedded" for the directly as was done in the past.
With the move to 2.0, I want to remove this legacy since there isn't
much point to keeping it.
