[jboss-osgi-dev] [JBoss OSGi Development] - 3.6.3 Optional Packages

3.6.3 Optional Packages https://jira.jboss.org/jira/browse/JBOSGI-143 A bundle can indicate that it does not require a package to resolve correctly, but it may use the package if it is available. For example, logging is important, but the absence of a log service should not prevent a bundle from running. Optional imports can be specified in the following ways: Dynamic Imports – The DynamicImport-Package header is intended to look for an exported package when that package is needed. The key use case for dynamic import is the Class forName method when a bundle does not know in advance the class name it may be requested to load. Resolution Directive – The resolution directive on an import definition specifying the value optional. A bundle may successfully resolve if a suitable optional package is not present. The key difference between these two mechanisms is when the wires are made. An attempt is made to establish a wire for a dynamic import every time there is an attempt to load a class in that package, whereas the wire for a resolution optional package may only be established when the bundle is resolved.
