-------------------------------
Summary: NPE in Application iTests
Key: ARIES-931
URL: https://issues.apache.org/jira/browse/ARIES-931
Project: Aries
Issue Type: Bug
Components: Application
Reporter: John Ross
The following NPE from application-itests will occasionally occur during the
Aries build.
java.lang.NullPointerException
at
org.apache.aries.application.runtime.framework.management.SharedFrameworkPreResolveHook.collectFakeResources(SharedFrameworkPreResolveHook.java:161)
The NPE occurs because fwMgr.getSharedBundleFramework() returns null since the
shared bundle framework was not created earlier.
org.apache.aries.application.runtime.framework.management.BundleFrameworkManagerImpl
- Caught exception
org.apache.aries.application.management.spi.repository.ContextException: Unable
to create or start the shared framework composite bundle null
at
org.apache.aries.application.runtime.framework.management.SharedBundleFramework.createSharedBundleFramework(SharedBundleFramework.java:83)
The shared bundle framework was not created due to a
ConcurrentModificationException in the Equinox framework.

The CME is a known issue and was fixed as of Equinox 3.7.2. Currently, the
application-itests run against both Equinox 3.5.0 and 3.7.0, which are subject
to the CME. Unless running against these frameworks is absolutely necessary,
I'd like to propose that the itests be executed against 3.8, available in Maven
Central, instead in order to avoid these potential "false positives" in the
Aries build test results. The other configurations can remain in order to run
locally when necessary but would be commented out.
