Java error when trying to open property inspector

I'm using Matlab 2019a with TAH licence. I installed Matlab on home directory because usr folder does not have enough space (OS: Ubuntu 19.10). Matlab works fine but when I try to open property inspector of a plot I get following error. Thank you for your help.

Dear all,

I experience the same kind of problems with R2019a on Linux Ubuntu 18.04

See details below.

Is there any update on this topic ?

best regards,

François.

When I try the figure properties editor (I don't like the new one by the way) I get in matlab window line :
