Answer 1

it seems as if you are using new version of Stanford NLP parser. in new version of this parser constructors are not used to allocate memory, instead we are having dedicated functions . you can use :

LexicalizedParser lp = LexicalizedParser.loadModel("englishPCFG.ser.gz");

you can use various overloads of this API.
