Is the Java Model the result of the AST build (from the parsing)? If not, 
then what does it stand for?  When is the index& Java Model build? What do 
you mean by types proposals (only when ASTNode is a type?)

Is the parser applied for the Error highlighting working in some 
incremental way, or does it do full parsing?
