I have an issue running MATLAB 2020a on Ubuntu 20.04. MATLAB starts up properly but it shows the
PostVMInit failed to initialize com.mathworks.mwswing.MJStartupForDesktop
message.
Then, when I want to inspect a variable all I get is a series of errors, e.g.:
Exception in thread "AWT-EventQueue-0": java.lang.NoClassDefFoundError: Could not initialize class com.mathworks.mwswing.MJStartupForDesktop

From this moment ANY command window output is followed by a series of error meassages of this type:
Exception in thread "AWT-EventQueue-0": java.lang.NoClassDefFoundError: Could not initialize class com.mathworks.widgets.spreadsheet.SpreadsheetColor
I don't know if it's related, but MATLAB starts with SOTWARE OPENGL rendering.
NOTE: If I run MATLAB as root the problem is gone!
Non-successfull solutions tried:
I tried to use the system's JVM (openjdk 8) setting the MATLAB_JAVA variable accordingly.
