OSGi bundle resolving problems

[thjaeckle]

Hi.
With the latest 2.0.0-RC8 there seem to be some problems with the OSGi manifests.
When trowing following bundles into into a Felix container I get 2 errors.

The Bundles

(which are transitive dependencies of async-http-client):

• netty-transport-4.0.34.Final.jar
• netty-handler-4.0.34.Final.jar
• netty-common-4.0.34.Final.jar
• netty-codec-4.0.34.Final.jar
• netty-codec-http-4.0.34.Final.jar
• netty-buffer-4.0.34.Final.jar
• javassist-3.18.1-GA.jar
• netty-reactive-streams-1.0.2.jar
• async-http-client-2.0.0-RC8.jar
• netty-codec-dns-2.0.0-RC8.jar
• netty-resolver-dns-2.0.0-RC8.jar
• netty-resolver-2.0.0-RC8.jar

Error 1

Error 2

2016-02-04 12:51:46,430 | WARN  | ? | org.apache.felix.fileinstall | Error while starting bundle: file:/D:/felix/osgi/deploy/async-http-client-2.0.0-RC8.jar

*Edit: the Error 2 probably is because artifact netty-reactive-streams-1.0.2.jar is no OSGi bundle (no MANIFEST exports).

Frankly, I personally have no usage for OSGI.
Contributions welcome.

Hi!

Which Felix version do you use?

Could you please show output of lb command from felix command line when you get this error?

[slandelle]

Probably related to #1132.

I'll be clear: I personally don't have a usage for OSGI. In order to fix #1132, I removed this Felix crap.
If anyone really needs OSGI support, please contribute.

So no support for OSGi... super sad..!!! :(

As stated in the labels, contributions welcome.

[piyushGoyal2]
