Amichai Rothman commented on DOSGI-162:
---------------------------------------

As it turns out, the Felix Framework bundle indeed contains a copy of the 
org.osgi core packages, so even when the osgi bundle versions were changed, it 
was still compiling against the older osgi API. Updating the corresponding 
Felix version caused it to actually compile against the newer osgi API. I've 
added a comment explaining this in the pom, plus the two missing fixes (missing 
cast and one forgotten dependency version fix).

> When trying to compile against the OSGi core library releases 4.3.0, 4.3.1 
> and 5.0.0, there are several compilation errors. The fix includes:
> - cast null to String when calling BundleContext.getServiceReferences (an 
> overloaded method was added, and passing null now causes ambiguity)
> - fix generic types and use of Properties (which extend Hashtable<Object, 
> Object>), by using Dictionary<String, String> implemented as 
> Hashtable<String, String> instead.
> - split between osgi.version and osgi.enterprise.version POM properties since 
> the two have independent release versions (specifically, there are no 
> enterprise 4.3.0/4.3.1 releases).
> The fix is backward-compatible, so compilation is successful on 
> 4.2.0/4.3.0/4.3.1/5.0.0 with the patch applied. However, there are still 4 
> unit tests which fail in the later versions, but these are unrelated to the 
> compilation errors and have to do with other dependency library versions (the 
> patch does not change any versions). So consider this the first step.
