Inconsistent container state if uninstalling bundles in the a bundle activators
start method during framework startup.
----------------------------------------------------------------------------------------------------------------------
Key: FELIX-3387
URL: https://issues.apache.org/jira/browse/FELIX-3387
Project: Felix
Issue Type: Bug
Components: Framework
Affects Versions: framework-4.0.2
Environment: JRE 1.6
Reporter: Marcel Hanser
If uninstalling a bundle in the BundleActivator#start() method like in the
small snipplet below, and the container is in his starting phase the container
will never leave this state. In this state its not possible to start any bundle
or to shutdown the container with the gogo shell. The pretty same issue occurs
if the bundle is cached and it uninstalls a also cached bundle.
To reproduce:
1) Download current Felix 4.0.2 distribution.
2) create two bundles,
a) one with the Activator below.
b) one with the symbolicname "usual.bundle.usual.bundle".
4) put them into e.g. the "extra_bundles" folder
5) add
felix.auto.start.1=file:extra_bundles/test-0.0.1-SNAPSHOT.jar \
file:extra_bundles/usual.bundle-0.0.1-SNAPSHOT.jar
to the config.properties
6) execute java -jar bin/felix.jar
You will see
C:\Users\...\Desktop\felix-framework-4.0.2>java -jar bin/felix.jar
uninstalling bundle: usual.bundle.usual.bundle [7]
