--------------------------------
Hi Richard,
Thanks for the patch. I tried it but I got deadlock problem for the following
situation:
Bundle71 (in repo) : Depends on Bundle72
Bundle72 v1 (in repo) : depends on bundle73
Bundle72_2 v2 (in eba) : Depends on Bundle.invalid // This should not be
picked up
Bundle73 (in eba) : No Dependencies
I expect bundle71, bundle71 v1 and bundle73 are installed in framework.

Please let me know if you need more information.

> Key: FELIX-1792
> URL: https://issues.apache.org/jira/browse/FELIX-1792
> Project: Felix
> Issue Type: Bug
> Components: Bundle Repository (OBR)
> Affects Versions: bundlerepository-1.4.2
> Environment: n/a
> Reporter: david small99
> Assignee: Richard S. Hall
> Fix For: bundlerepository-1.6.0
>
>
> I have one bundle bundle1, which imports a package called com.obr.bundle
> Bundle1's manifest:
> Manifest-Version: 1.0
> Ant-Version: Apache Ant 1.7.0
> Bundle-ManifestVersion: 2
> Bundle-Name: Bundle Plug-in
> Bundle-SymbolicName: com.obr.bundle1
> Bundle-Version: 1.0.0
> Export-Package: com.obr.bundle1
> Import-Package: com.obr.bundle;version="[1.2.0.999,3.2.2.bz]"
> There are two bundles in my repositories, bundler2 and bundle 3. Both of them
> export package com.obr.bundle. Below are their manifest files.
> Bundle2
> Manifest-Version: 1.0
> Ant-Version: Apache Ant 1.7.0
> Bundle-ManifestVersion: 2
> Bundle-Name: Bundle Plug-in
> Bundle-SymbolicName: com.obr.bundle2
> Bundle-Version: 1.0.0
> Bundle-Vendor: xxx
> Import-Package: a.b.c
> Export-Package: com.obr.bundle;version=3.2.2.blah
> Bundle3:
> Manifest-Version: 1.0
> Ant-Version: Apache Ant 1.7.0
> Bundle-ManifestVersion: 2
> Bundle-Name: Bundle Plug-in
> Bundle-SymbolicName: com.obr.bundle3
> Bundle-Version: 1.0.0
> Import-Package: a.b.c
> Export-Package: com.obr.bundle;version=3.1
> As you can see, both bundle2 and bundle3 meet the requirements of bundle1. I
> hope the highest package version, which is bundle2, is chosen by felix obr.
> However, sometimes bundle 3 was chosen instead of bundle2. The behaviour is
> random.
> Am I right to say that the Felix obr runtime just picks the first bundle that
> meets the requirements and then stop searching for any more eligible bundles?
> Thanks
