javafx: XQuartz on Mac

When using X11 forwarding over XQuartz on Mac, JavaFX programs sometimes result in the following error:

-bash-4.3$ java HelloJavaFX 
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  149 (GLX)
  Minor opcode of failed request:  24 (X_GLXCreateNewContext)
  Value in failed request:  0x0
  Serial number of failed request:  28
  Current serial number in output stream:  29
-bash-4.3$

This magic command line that you run at the Mac command line seems to fix the problem, as suggested by this internet discussion, which referenced this other bug report
