View Name/ Template Name is truncated when getAbsoluteViewURIInternal() is used

[zzzyy]

Expected Behavior

When groovyPageRenderer.render(view: "index") is used, internally when getAbsoluteViewURIInternal() is used, the full url should be given instead of url with truncated first character of the view page.

Actual Behaviour

instead of getting .../grails-app/views/index.gsp, the getAbsoluteViewURIInternal () is returning .../grails-app/views/ndex.gsp. 'i' is being truncated. Most likely due to the code:
String tmp = viewName.substring(1,viewName.length());

Steps To Reproduce

Try to render a gsp page into HTML using PageRenderer. Here is the snippet:
String html
try{
html = groovyPageRenderer.render(view: "index")
}catch (Exception e){
println "Error "
e.printStackTrace()
}

    the html value is always '' because index is being truncated to ndex
