Cannot find a Grails controller with 2 consecutive upper case letters -

i have created controller named ebookcontroller. when start grails web application, application returns 404 on ebook\index page.

i change controller name ebookcontroller , applications works correctly when request ebook\index.

can grails handle 2 or more consecutive upper case letters in controller name?

section 8.8 of spec @ http://download.oracle.com/otn-pub/jcp/7224-javabeans-1.01-fr-spec-oth-jspec/beans.101.pdf?authparam=1470678357_57f26d616e55176cadc14024648f450c includes following:

however support occasional use of upper-case names, check if first 2 characters of name both upper case , if leave alone.

that means ebook map ebook not ebook
