Incorrect string capitalization

Reports strings in method parameters and return values annotated with @Nls and having the capitalization parameter to conform to capitalization rules existing in most platform UI guidelines.

Example:

  void setTitle(@NlsContexts.DialogTitle String title) {}
  setTitle("This is sentence capitalization but should be title"); 

After the quick-fix is applied:

setTitle("This Is Sentence Capitalization but Should Be Title");
