ApiModelProperty definition and generation of static html documentation

I use 2 different ways to generate static html from a swagger/yaml 2.0 model:

 

1. swagger to static HTML, using org.swagger2html.Swagger2Html

a. works fine (generates static HTML file) with no ApiModelProperty definition

b. throws OOM error when add ApiModelProperty definition and try to generate static HTML

 

2. Using Codegen 1.4.0-SNAPSHOT base code

a. for html option does NOT generate ApiModelProperty definition in static HTML

b. for html2 option does NOTgenerate ApiModelProperty definition in static HTML

 

Any ideas?
