I tried the rudimentary standalone test for com.jogamp.opengl.  That appears to work.

I switched to v2.3.2 of jogamp-fat-all, keeping Java3d 1.7.  For a half-second, I was able to rotate a shape with normal performance before it went back to extreme pausing with occasional blanking of the canvas for many seconds.  There are no exceptions or stack dumps.  Now I get a different warning,

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.jogamp.java3d.JoglPipeline (file:/C:/Users/steveVl/Documents/SolidSystems/solidwork/java3d-1.7/j3dcore.jar) to method sun.awt.AppContext.getAppContext()
WARNING: Please consider reporting this to the maintainers of org.jogamp.java3d.JoglPipeline
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release  

I tried the version of java I was using earlier, 1.8.0_241, and although the performance hang-up still existed, I did not get the above warning.

I checked my device drivers, they are all up-to-date.  Is there any additional configuration needed on Windows 10 other than having the java, java3d, and jogamp libraries installed and on the build path (specified in Eclipse as given on the web page)?

I could not find any online guidance or example of JCanvas3D (which had not worked a few years ago when I did the Windows 7 testing), but I tried switching anyway and consistently get the following.  Is it worth trying JCanvas3D, and are there any examples or guidelines for setting this up?
