Hi Niko,

What you were experiencing was a known issue [1]. It has been fixed for the 4.4.9 version of OMERO.server [2].
>From now on, on both the 5.0 and 4.4 branches, the JNLP file will not be cached due to a specific
HTTP header sent by the server to the client web browser. This will cause an automatic update (if needed) of the
JAR files each time you use the Webstart functionality.

Regards,
Blazej
