Re: [X2Go-User] Matlab in X2go
https://stackoverflow.com/questions/34188495/how-can-i-work-around-the-classcastexception-in-java2d-bug-id-7172749 describes that problem and offers a workaround (JVM option -Dsun.java2d.xrender=false) Unfortunately that workaround is bad for the x2go environment and will probably slow down your desktop. Normally we recommend to do the opposite and ENABLE xrender rendering because then the functions that NX can accellerate are used.
