ScopeDescs incorrect in Java 8

[David Griffiths]

Ok, will do. I noticed a mismatch between the assembler produced by my use
of HTMLGenerator and that from -XX:CompileCommand=print so need to figure
out if I'm doing something stupid first (e.g. I see the use of "7.0"
results in a constant section being produced and codeBegin() !=
getEntryPoint() so could be something related to that).

Cheers,

David
