Subject [jira] [Created] (FELIX-3284) NullPointerException may be thrown if asynchronous bundle update fails
Date Mon, 19 Dec 2011 08:14:30 GMT
NullPointerException may be thrown if asynchronous bundle update fails

                 Key: FELIX-3284
                 URL: https://issues.apache.org/jira/browse/FELIX-3284
             Project: Felix
          Issue Type: Bug
          Components: Web Console
    Affects Versions: webconsole-3.1.8
            Reporter: Felix Meschberger
            Assignee: Felix Meschberger
             Fix For: webconsole-3.2.0

If the web console bundle gets restarted while a bundle is being updated in the BaseUpdateInstallerHelper
thread and an exception happens during the update, the log message cannot be written causing
a NullPointerException. This factually hides the actual problem.

The fix is to catch any exception when trying to log the message and just write the error
to std err to at least get some indication of problems.

One such potential situation is failing to update the web console bundle itself (e.g. due
to missing dependencies)
