[jboss-jira] [JBoss JIRA] Created: (JBCL-137) Add support for OSGi Fragments

Add support for OSGi Fragments ------------------------------ Key: JBCL-137 URL: https://jira.jboss.org/jira/browse/JBCL-137 Project: JBoss ClassLoader Issue Type: Feature Request Reporter: Thomas Diesler Fragments are bundles that can be attached to one or more host bundles by the Framework. Attaching is done as part of resolving: the Framework appends the relevant definitions of the fragment bundles to the host's definitions before the host is resolved. Fragments are therefore treated as part of the host, including any permitted headers; they must not have their own class loader though fragments must have their own Protection Domain. When attaching a fragment bundle to a host bundle the Framework must perform the following steps: 1 Append the import definitions for the Fragment bundle that do not con- flict with an import definition of the host to the import definitions of the host bundle. A Fragment can provide an import statement for a private package of the host. The private package in the host is hidden in that case. 2 Append the Require-Bundle entries of the fragment bundle that do not conflict with a Require-Bundle entry of the host to the Require-Bundle entries of the host bundle. 3 Append the export definitions of a Fragment bundle to the export defini- tions of the host bundle unless the exact definition (directives and attributes must match) is already present in the host. Fragment bundles can therefore add additional exports for the same package name. The bundle-version attributes and bundle-symbolic-name attributes will reflect the host bundle. A host and a fragment conflict when they cannot resolve to provide a consis- tent class space. If a conflict is found, the Fragment bundle is not attached to the host bundle. A Fragment bundle must enter the resolved state only if it has been success- fully attached to at least one host bundle. During runtime, the fragment's JAR is searched after the host's bundle class path -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
