GMSC 2018 Update 3 - plugin migration issue - swingx-1.6.1.jar



We have some plugins which worked on GMSC 2018 update 2.

We migrated some of them to GMSC 2018 u3 without problem.

One of them doesn't work. It uses the swingx-1.6.1.jar external library. I cannot find any restriction about this library (at least in the v9 and v10 deprecated list).

No problem in Eclipse project. Just an error when lauching GMSC with the signed jars. The error is:

Any idea?

Thank you.

Hi Yohann,


it is probably not part of the jar, shouldn't this be swingx-all-1.6.1.jar?

Hello Stefano,


You were right. This was not part of the specified jar but included in the all.jar.

My plugins work now in GMSC 2018 u3.


Thank you!

The problem were elsewhere.

We used to use *.jnlp files to reference plugin dependencies.

External libs were put in subfolders.

I didn't notice that with GMSC 2018 u3 all jars, including dependencies, have to be placed directly in the "plugins" folder.
