java security no longer accepts security levels below "HIGH"  If you cannot (or won't) rewrite sage_math
to use a non-java jmol (see jsmol for example), then explain how I'm supposed to fix:
"Application Blocked by Java Security
 
For security, applications must now meet the requirements for the High or Very High security settings, or be part of the Exception Site List, to be allowed to run.
 
Name:  jmolApplet0
Location: file://
Reason: Your security settings have blocked an application from running due to missing a "Permissions" manifest attribute in the main jar.
"
 
I've added /usr/lib/jvm/jdk1.8.0_25/jre/lib/applet/jmol.jar to the Exception Site List, but STILL java throws up the above-quoted dialog box!  BTW, just where is the jmol code supposed to be located in sage_math?

Hi! It is precisely for such reasons that we (thanks to a lot of good work by Jonathan Gutow and Volker Braun) have jsmol as the default 3d viewer for Sage 6.4.  Try it out!
 
That said, it probably depends on your Java if you do plan to use Java applets for better rotation of dense plots and such; this is the first I've seen of a security issue of this kind (as opposed to problems with IcedTea or certain browsers) where it isn't allowed at all, but Java is in principle allowed. 
 
Finally, the jmol jar files are in the Sage tree, shouldn't be in /usr/lib ... ?  Maybe that is a different jmol instance?
