RDFCASConsumer and Java 5
UIMA components are spec'd to require Java 5. However, the RDFCASConsumer
project depends on classes from the clerezza project (here's one:
org/apache/clerezza/rdf/core/MGraph.class) which are compiled with Java 6.
Because of this, when building RDFCASConsumer, I get a compile failure:

How should we fix this? Does Clezerra really require Java 6? Can we depend on
something else?

I don't think we can distribute Java 5 jars. (They're not Apache licensed :-) ).

Hi again,
I successfully built Clerezza with Java 5 and made RDFCASConsumer run with
the 5-versioned Clerezza dependencies.
I am wondering if It may be worth having bundled Java 5 jars inside a lib
directory (system scoped dependency) to avoid having to run such a custom
build.
Otherwise I think we should switch to directly use Jena, drop Clerezza and
do some coding.
Cheers,
Tommaso

Thanks Marshall, for notifying this, I missed that.
The possible solutions are: build Clerezza with Java 5 (no code change) or
use directly Jena which should be Java 5 compatible from 0.8.2 onwards (need
some basic code improvement).
I'm going to test the first option now and let you know soon.
Cheers,
Tommaso
