RFR: 8035618 : Four api/org_omg/CORBA TCK tests fail under plugin only

[Seán Coffey]

I'm looking to port this fix from JDK 8 to 9. Other changes were made 
for JDK 9 given that we have access to the 
javaAwtAccess.getAppletContext() method when using JDK 8 as the boot 
strap JDK for CORBA. Direct access to the sun.awt.AppContect class has 
been removed.
