-# OSGI Notes
-
-1. Dependency on Third Party Bundles
-    Some adapters depend on third party libraries (bundles).
-    Spring hosts the Enterprise Bundle Repository (EBR) at
-        https://ebr.springsource.com/repository/app/, where you can download
-        many third-party JARs as valid OSGi bundles.
-    If a particular bundle is not available in Spring's EBR, there are tools
-       that can convert a regular JAR to a bundle JAR. One of them is Bundlor
-       http://www.springsource.org/bundlor which can auto-generate an OSGi
-       MANIFEST.MF as part of standard project lifecycle or simply convert a
-       non-bundle JAR to a bundle JAR.
-2. Boot delegation
-    Some adapters depend on extension packages that are available to the boot
-    class loader. As a case in point, the Feed Adapter depends on
-    com.sun.syndication.feed. Since by default OSGi only loads java.* from the
-    boot class loader, other packages that must be loaded from the boot class
-    loader can therefore be specified with the
-    'org.osgi.framework.bootdelegation' System property.
-    For example:
-        org.osgi.framework.bootdelegation=com.sun.*,org.w3c.*. . . .
