###### OSGI Notes ######
1. Dependency on Third Party Bundles
Some adapters depend on third party libraries (bundles).
Spring hosts Enterprise Bundle Repository (EBR) 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 regular
JAR to a bundle JAR. One of them is Bundlor http://www.springsource.org/bundlor which can auto-generate
MANIFEST as part of standard project lifecycle or simply convert non-bundle JAR to a bundle JAR.
2. Boot delegation
Some adapters depend on extension packages that are available to the boot class loader.
For example; 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.*. . . .
