Hi Charles,
According to
http://java.sun.com/docs/books/jls/second_edition/html/interfaces.doc.html#236431
an interface can contain both interface and class declarations, as in:
interface foo {
class bar { }
interface baz { }
}

To fix the java.tree.g grammar, just add typeDefinition to the
interfaceBlock production so it looks like this:
interfaceBlock
: #( OBJBLOCK
( methodDecl
| variableDef
| typeDefinition
)*
)
;
Hope that helps.
