Not a fan of spawning a new process every time JSDT needs to parse 
Javascript.
Parsing actually happens a lot on JSDT for instance every hover, setting 
a breakpoint potentially causes a parse request.

Yes, this is an option that I have not experimented with. It may just 
work for parser use case.

The current mechanism of JSDT works with the internal AST model. For 
instance when setting a breakpoint JSDT
uses AST model to determine the exact location to set the breakpoint. 
The alternate to converting the AST received
from parser is to modify JSDT in all places to use the new model. Also 
you should consider that the AST model received
from acorn/esprima does not have a Java model counterpart at this time.
