java error no ComponentUI class for javax.swing.JScrollPane

I updated from Matlab 2016a to 2017b on my redhat scientific linux rel 6.6 box, when I run just about anything I get the following errors (and as indicated by the messages, no scroll bars) in my matlab window:

I experienced the same problem, and the following command worked for me. I'm using ubuntu 16.04 LTS.

Open the terminal and type as follows, just before executing the command 'matlab'.

export MATLAB_JAVA=/usr/local/MATLAB/R2017b/sys/java/jre/glnxa64/jre

The problem seems to be occurred from JAVA run-time version mismatch. This site was very helpful. https://jp.mathworks.com/matlabcentral/answers/103089-matlab-java-virtual-machine-jvm
