[jira] [Resolved] (FELIX-3946) NullPointerException in
BundleServlet.bundleDetails when not called through HTTP
[ https://issues.apache.org/jira/browse/FELIX-3946?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Felix Meschberger resolved FELIX-3946.
--------------------------------------
Resolution: Fixed
Fixed as indicated in the initial description in Rev. 1452202:
In addition the "nfo" information generated by the BundleInfoProvider services is now also properly rendered in the printConfiguration output: For each block of BundleInfo objects the block key is printed as well as the BundleInfo.name fields. For example the services used by a bundle are printed like this:
> Used Services:
> Service #1 of type(s) [org.osgi.service.packageadmin.PackageAdmin]
> Service #45 of type(s) [org.apache.felix.webconsole.bundleinfo.BundleInfoProvider]
> Service #41 of type(s) [org.osgi.service.http.HttpService, org.apache.felix.http.api.ExtHttpService]
> Service #2 of type(s) [org.osgi.service.startlevel.StartLevel]
> NullPointerException in BundleServlet.bundleDetails when not called through HTTP
> --------------------------------------------------------------------------------

> Key: FELIX-3946
> URL: https://issues.apache.org/jira/browse/FELIX-3946
> Project: Felix
> Issue Type: Bug
> Components: Web Console
> Affects Versions: webconsole-4.0.2
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Fix For: webconsole-4.0.2
>
>
> With the introduction of the Inventory bundle and the migration of ConfigurationStatusPrinter to InventoryPrinter, these services may be called through other channels than through the Web Console over HTTP.
> Thus the appRoot and pluginRoot parameters to the BundleServlet.writeJSON method may be null and therefore the following code in the bundleDetails method throws a NullPointerException:
> > bundleInfoDetails(jw, bundle, pluginRoot.substring(0, pluginRoot.lastIndexOf("/")), locale);
> A number of fixes are required:
> * Prevent NPE at this code location
> * Clarify BundleInfoProvider interface that webConsoleRoot may be null
> * Fix ServicesUsedInfoProvider to create VALUE type BundleInfo if webConsoleRoot is null
