It looks like you are using the new version of the Stanford NLP parser. in the new version, the constructors of this analyzer are not used to allocate memory; instead, we have specialized functions. you can use:

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

You can use various overloads of this API.

Stanford documentation for various overloads loadModel
