NPE in Filter
--------------
Key: FELIX-2417
URL: https://issues.apache.org/jira/browse/FELIX-2417
Project: Felix
Issue Type: Bug
Affects Versions: framework-3.0.0
Environment: java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)
Reporter: Martin Zdila
After upgrading framework from 2.0.5 to 3.0.0 I am getting many NPE exceptions
"Cannot register Component".
I can't identify the core of the problem, but from what I see: in the
org.apache.felix.framework.FilterImpl on line 145 the name =
"service.factoryPid" but m_map doesn't contain such entry and so the key is set
to null. The next call on the line 147 fails because key cannot be null in
Hashtable.get(key).
