Hi!

I tracked down the issue: There seems to be a version conflict regarding
spring: Omero uses 2.0.6, whereas I'm trying to use the omero client lib
 inside our application which uses spring 2.0.8. I also tested this by
writing an example prog which works using spring 2.0.6 but doesn't when
use 2.0.8.

I get the following error using Spring 2.0.8.

Any ideas as how to solve this ? Maybe recompile using Spring 2.0.8 ?

TIA, Simon
