OpenCV plugins not working (? java issue)

[Rainer M. Engel]

Hi..

I recently came across an update site with OpenCV based plugins (2).
Before that I was testing a separate template matching plugin (1).

To get the plugin from the update site I also updated my FIJI and right
now none of the mentioned plugins is working.

1) https://sites.google.com/site/qingzongtseng/template-matching-ij-plugin
On their site is an updated version for Java 1.8 available, which did
not solve the error for me.

Is there already a solution to this issue probably related to my used
java version? I assume this might be a problem for others as well.

Kind regards,
Rainer
