Regression with native library handling
---------------------------------------
Key: FELIX-1580
URL: https://issues.apache.org/jira/browse/FELIX-1580
Project: Felix
Issue Type: Bug
Components: Framework
Affects Versions: felix-2.0.0
Environment: generic, JDK6, tested on Windows & Linux
Reporter: Holger Hoffstätte
Priority: Critical
I tried to update to felix-2.0.0 but my bundles with native code would not
install anymore, even though they work fine under felix-1.8.1 and equinox. The
following error showed up for no good reason:
org.osgi.framework.BundleException: Activator start error in bundle

Through trial-and-error I have found the rather confusing conditions under
which this error shows up:
- a library is not found in the bundle (code passes a nonexisting name to
System.loadLibrary())
- multiple libraries are _correctly_ specified in the Bundle-NativeCode header!
There might be other confusing combinations. ;)
I traced this back to the changes to R4Library in r790963 (Add support for
configurable native library extensions. (FELIX-1298)) where the match() method
was modified. It seems that the "exts" array is empty and therefore leads to
the AIOOB later.
