RFR : 8039131: CORBA build issue : sun.misc.JavaAWTAccess

[Seán Coffey]

The CORBA build issue continues. I was incorrectly using 7u40 as the 
bootstrap JDK. 7u7 is still the version that RE uses and that causes an 
issue since sun.misc.JavaAWTAccess wasn't introduced until 7u9.

The fix proposed is short term. There's a discussion underway on 
build-dev to bump the JDK bootstrap version to JDK 8 for JDK 9 builds.

Build and tests are good. I've used 7u7 this time for bootstrap!
