Martin Zdila commented on FELIX-1032:
-------------------------------------
I found out that I am getting NPE even if I do no updates at all. I just start
the framework, and it will install/start all the bundles in the bundle
directory. The resources are read in the thread created by Jetty as a reaction
to the HTTP request. I get more NPEs if I update the bundle (A or B). When
updating, I do nothing else so the code in the bundles being updated are not
executed in that moment. All the bundles are in the Active state. The scan
happens on the bundle activation. It also checks if event is
BundleEvent.STARTED. I am still trying to prepare a testcase, but NPEs are
still random and very rare o my testcase :-(.

> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: felix-1.4.1, felix-1.6.0, felix-1.6.1, felix-1.8.0
> Environment: Linux bono 2.6.28-6-generic #17-Ubuntu SMP Fri Jan 30
> 15:34:36 UTC 2009 i686 GNU/Linux
> java version "1.6.0_13"
> Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
> Java HotSpot(TM) Client VM (build 11.3-b02, mixed mode, sharing)
> Reporter: Martin Zdila
> Priority: Critical
> Attachments: hack.patch

> Note that also affected is felix-1.6.0 (it is not in the list).
> I am often getting NPE with the following code:
> new URL("bundle://66.0:0/somewhere/my.resource" /* or any other bundle:// URL
> */).openStream();
> java.lang.NullPointerException
> at java.util.zip.Inflater.ensureOpen(Inflater.java:336)
> at java.util.zip.Inflater.getBytesWritten(Inflater.java:296)
> at java.util.zip.ZipFile$1.available(ZipFile.java:243)
> at
> org.apache.felix.framework.URLHandlersBundleURLConnection.connect(URLHandlersBundleURLConnection.java:125)
> at
> org.apache.felix.framework.URLHandlersBundleURLConnection.getInputStream(URLHandlersBundleURLConnection.java:134)
> at java.net.URL.openStream(URL.java:1009)
> It is not allways reproducible. The first call causes the NPE and the second
> call with the same URL string goes without problems.
