Bug#1076673: jameica: Exception in thread "main" java.lang.UnsatisfiedLinkError: Could not load SWT library.

Hi Jochen,

some additional information

when symbolic linking the libraries from /usr/lib/jni to
~/.swt/lib/linux/aarch64 the application works - but needs relinking 
when the libraries are updated.
