All right, make sense to me to deploy such JAI bundles only once and
not every time udig is build. Properly it would be better to setup
this as an separate project (independently from udig) and use it in
udig (as an osgi based application).

I thought about the JAI/imageio things. IMHO this bundles have not to
be build every time udig bundles are build. Means that the Version is
always the same (JAI 1.1.3/ ImageIO 1.1) since udig 1.1.1 I guess. In
the same universe I would see the com.lowagie.itext and
org.apache.log4j bundles (log4j can also be taken from osgi-fied
com.springsource.org.apache.log4j bundle - which can be resolved from
public springsource maven repository).

IMHO, every thirdparty dependency that's included in the standard
build should be kicked out and can be resolved during the build (maven
dependency + target platform (p2) resolver).

Still confused? IRC?
