[X2Go-Dev] Bug#645: (no subject)

[Miguel Dilaj]

Hi all,

If you are using JDK8, and running the offending program using strace 
causes entries like this one:

      java.lang.ClassCastException: sun.awt.image.BufImgSurfaceData 
cannot be cast to sun.java2d.xr.XRSurfaceData

Then it's not an X2Go bug, it's a Java bug. See 
http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7172749

Many Java programs are affected when run over X2Go.
The only workaround I've found is downgrading to JDK7, where the bug is 
not present.
Presumably Oracle will solve it in JDK9, but I don't have the time to 
extensively test it.
Hope that helps!
Kind regards,

Miguel
