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.
