MATLAB: Java.langU​nsatisfied​LinkError problem

java.langlinuxmatlab editormatlab window

Hi all,
I'm using MATLAB 2015a in Linux Ubuntu 19.04.
My Matlab interface is a mess with the buttons of the interfaces.
Sometimes the editor buttons do not work, sometimes the buttons and clicking in the main matlab window do not work.
I get the following error when clicking in the Community button, for example:
Exception in thread "XPCOMMessageLoop" java.lang.UnsatisfiedLinkError: /usr/local/MATLAB/R2015a/sys/jxbrowser/glnxa64/xulrunner/xulrunner-linux-64/libxul.so: /lib/x86_64-linux-gnu/libcairo.so.2: undefined symbol: FT_Get_Var_Design_Coordinates

Does anybody know how to solve such problem?

Hi , Finally I could solve this problem using this link:
https://podcloud.fr/podcast/tuxicoman/episode/undefined-symbol-ft-get-var-design-coordinates
The solution is very simple, rename libfreetype.so.6 in the matlabroot/bin/glnxa64
sudo mv matlabroot/bin/glnxa64/libfreetype.so.6  matlabroot/bin/glnxa64/BK_libfreetype.so.6
I have tested it with 3 version of Matlab and works for them
