Find attached the patch that worked for me (applied on trunk and using solr 
4.4). It has not been tested in depth, so please use it under your 
responsability.

note: I've attached it as I havent found the msoko...@safaribooksonline.com 
proposed one.

I applied the patch with no complaints and rebuild fails in maven
javac 1.7.0_71
Building on Linux X86-64 environment if it matters

Can you really rebuild this in maven???
