Re: Felix does not start with bootdelegation="*"
------------------------------------------------
Key: FELIX-463
URL: https://issues.apache.org/jira/browse/FELIX-463
Project: Felix
Issue Type: Bug
Components: Framework
Affects Versions: 1.0.0
Environment: JDK 1.5.0_06 or 1.6 on Solaris 10/x86
Reporter: Sahoo
Priority: Critical
I am having trouble starting Felix when I use
-Dorg.osgi.framework.bootdelegation="*". When I run using the following command:
'/usr/bin/java -Dorg.osgi.framework.bootdelegation="*" -jar bin/felix.jar', it
fails like this:
WARNING: *** Class 'org.apache.felix.shell.impl.Activator' was not found.
Bundle 1 does not import package 'org.apache.felix.shell.impl', nor is the
package exported by any other bundle or available from the system class loader.
*** (java.lang.ClassNotFoundException: *** Class
'org.apache.felix.shell.impl.Activator' was not found. Bundle 1 does not import
package 'org.apache.felix.shell.impl', nor is the package exported by any other

Section #3.8.4, Overall Search Order, of OSGi Service Platform Release 4 spec
does not clearly (or I don't understand it well enough) state what should be
the behavior. Relevant portions of the spec is given below:
/1 If the class or resource is in a java.* package, the request is delegated to
the parent class loader; otherwise, the search continues with the next step. If
the request is delegated to the parent class loader and the class or resource
is not found, then the search terminates and the request fails.
2 If the class or resource is from a package included in the boot delegation
list (org.osgi.framework.bootdelegation), then the request is delegated to the
parent class loader. If the class or resource is found there, the search ends.
/
Unlike point #1 above, point #2 does not mandate the search to terminate. I can
understand the search terminating for java.* packages, but why for other
packages? It seems Felix is terminating the search, therefore I am seeing this
failure. Can anyone please clarify this? I am using "*, " because I want to see
how I can make packages from some library jars available to bundles without
having to set org.osgi.framework.system.packages property?
I am hoping that if I add my library jars in system classpath and set
bootdelegation="*", the library jar's content will be automatically available
to other bundles even if I don't set org.osgi.framework.system.packages
property. Is this not going to work?
Thanks,
Sahoo
