Have you tested that with jtreg? I believe it may not work because of 
the way the SecurityManager is enabled inside the test (rather than 
using the jtreg java.security.policy option). You may find that you also 
need to grant those permissions to jtreg.jar since it is higher in the 
call stack. If that is the case, you are probably better off granting 
the permissions to all code, or restructuring the test to use the jtreg 
java.security.policy option, where jtreg installs its own 
SecurityManager to grant itself the proper permissions. However, that 
will require some code changes and granting some additional permissions 
to the test that are needed (for adding a security provider, etc) before 
it currently enables a SM. And that is probably more than you want to do 
for this fix.
