OBR cannot install JARs which have been encoded for transfer
------------------------------------------------------------
Key: FELIX-3191
URL: https://issues.apache.org/jira/browse/FELIX-3191
Project: Felix
Issue Type: Bug
Components: Bundle Repository (OBR)
Environment: Debian Testing, 64-bit
Reporter: Lionel Debroux
I recently had trouble installing bundles through the OBR: the JAR handling
code would spit errors about not being able to open the ZIP file.
With Wireshark, I tracked the problem down to the JAR file having been gzipped,
but not having been uncompressed on the computer side.
Even if they're not explicitly asked for it (which is the case when downloading
a bundle through the OBR), servers are allowed by the HTTP/1.1 spec to return
encoded content:
"If no Accept-Encoding field is present in a request, the server MAY assume
that the client will accept any content coding."
( http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.3 )
I worked around the problem the following way:

But I'm not sure whether that this is a proper fix, which is why I had posted
it to felix-users :)
