That is exactly what I have done! On a computer with 64-bit Xubuntu 
(Ubuntu with XFCE) 18.04 LTS with everything updated.

These files are exactly alike:
/usr/local/scilab/scilab-6.0.2/thirdparty/java/release
/usr/local/scilab/scilab-6.1.0/thirdparty/java/release

Please look further below!

I have now done that with a small, simple (Atom processor) computer with 
32-bit Windows 10 (updated) and there is no extra delay compared to 
Scilab 5.5.2 on the same computer (everything is pretty slow with Java 
GUI's compared to previous Scilab versions with Tcl/Tk!).
