<div class="block">The Permission Admin service allows management agents to manage the
permissions of bundles. There is at most one Permission Admin service present
in the OSGi environment.
<p>
Access to the Permission Admin service is protected by corresponding
<code>ServicePermission</code>. In addition <code>AdminPermission</code> is required to
actually set permissions.
<p>
Bundle permissions are managed using a permission table. A bundle's location
serves as the key into this permission table. The value of a table entry is
the set of permissions (of type <code>PermissionInfo</code>) granted to the bundle
named by the given location. A bundle may have an entry in the permission
table prior to being installed in the Framework.
<p>
The permissions specified in <code>setDefaultPermissions</code> are used as the
default permissions which are granted to all bundles that do not have an
entry in the permission table.
<p>
Any changes to a bundle's permissions in the permission table will take
effect no later than when bundle's <code>java.security.ProtectionDomain</code> is
next involved in a permission check, and will be made persistent.
<p>
Only permission classes on the system classpath or from an exported package
are considered during a permission check. Additionally, only permission
classes that are subclasses of <code>java.security.Permission</code> and define a
2-argument constructor that takes a <i>name </i> string and an <i>actions
</i> string can be used.
<p>
Permissions implicitly granted by the Framework (for example, a bundle's
permission to access its persistent storage area) cannot be changed, and are
not reflected in the permissions returned by <code>getPermissions</code> and
<code>getDefaultPermissions</code>.</div>
