I hope that the next release of Java 3D will avoid the shut down of Sweet Home 3D. I opened a defect about this problem on Java 3D web site at https://java3d.dev.java.net/issues/show_bug.cgi?id=527 ; please, vote for this issue and the more annoying issue https://java3d.dev.java.net/issues/show_bug.cgi?id=526 , and find other people that may vote for them.
When I'll be able to detect that 3D view printing fails, I'll change the program to report the problem to users in a dialog and avoid Sweet Home 3D shut down, but I'm not sure it will resolve your configuration issue anyway.
