For 

java.management/share/classes/sun/management/VMManagementImpl.java

I tried with a security manager and had to grant property access so that it worked properly.

For 

java.desktop/share/classes/sun/awt/FontConfiguration.java

this can be called from all code working with fonts so it needs to be handled too (e.g. PrivilegedAction).

Should I file a JBS issue for those two ?

Some of the others listed might indeed fall into the tool APIs you mentioned.
