pojogen-maven-plugin generates code that can't be compiled

If the `CsdlProperty` name contains hyphen character, for example my-column , the plugin generates corresponding java class attribute with getter and setter :

@org.apache.olingo.ext.proxy.api.annotations.Property(name = "my-column"..) 
String  my-column;
String getMy-column();
void setMy-column(String my-column);

This code can't be compiled. Please normalize the attribiute name while processing the template.
Thanks
