Do you know which?  The old settings have worked with every JDK
edition I have used.  (Note: there is a significant difference between
building the libraries in the java grade, i.e. what you normally
do and buildin the compiler in the java grade -- for the latter I think
we do have to bump the heap size in various spots.)
