-------------------------------------------

mvn:org.apache.clerezza/org.apache.clerezza.platform.security.conditions/0.5-incubating-SNAPSHOT
[ 2] [Active ] [ 2]

[ 9] [Active ] [ 2] mvn:org.apache.felix/org.apache.felix.scr/1.6.0
[ 10] [Active ] [ 2]
mvn:org.apache.felix/org.apache.felix.shell.tui/1.4.1
[ 11] [Active ] [ 2] mvn:org.apache.felix/org.apache.felix.shell/1.4.2
[ 12] [Active ] [ 2]
mvn:org.apache.felix/org.apache.felix.webconsole/3.1.2
All but a few bundles have AllPermissions, these are set in the following:
http://svn.apache.org/viewvc/incubator/clerezza/trunk/org.apache.clerezza.parent/org.apache.clerezza.platform.security/src/main/java/org/apache/clerezza/platform/security/BundlePermissionManager.java?view=markup
Whenever a permission-check (via AccessController) is perfomed, it seems that a
large amount of time is spent checking for the permission on the code-base
(guessing from the method names).

> Profiling Clerezza I found that a lot of time is spent in the implies method
> of org.apache.felix.framework.BundleProtectionDomain. I'm wondering if this
> could be made faster namely for Bundles that run with AllPermissions (as most
> bundles do not have any restriction but only the user/subject).
