NPE in BundleRevisionImpl.close() when uninstalling a bundle
------------------------------------------------------------
Key: FELIX-3160
URL: https://issues.apache.org/jira/browse/FELIX-3160
Project: Felix
Issue Type: Bug
Components: Framework
Reporter: Rob Walker
Assignee: Rob Walker
Priority: Minor
There seems to be a case where m_content can be null when uninstalling a
bundle, causing the following code to throw an NPE:
synchronized void close()
{
try
{
resolve(null);
}
catch (Exception ex)
{
((BundleImpl) m_bundle).getFramework().getLogger().log(
Logger.LOG_ERROR, "Error releasing revision: " +
ex.getMessage(), ex);
}
m_content.close();
I've added a simple check for null around the close in my version to avoid the
exception, which I'll check in.
I'm not sure of the scenarios where this can legally be null at this point, and
whether there's some nastier underlying circumstance that needs investigating.
We see it under the following circumstances:
* we register a listener that looks for framework STARTED
* when triggered, this iterates all bundles and performs an uninstall on ones
which we determine are zombies leftover from a previous run
Aside from the fact we're calling uninstall from inside an event handling
method, there doesn't anything else unusual about this code.
clears the exception. I'll check this i
