HR integration review request: #225107 - Pull Up Method To Abstract Super Class Ads Extraneous Comments

Description:
http://netbeans.org/bugzilla/show_bug.cgi?id=225107

When refactoring copies parts of code from one file to another, some 
code snippets may incorrectly contain duplicates of comments from the 
target file. The bug does not manifest itself in development builds 
because when assertions were enabled, additional debugging checks were 
done and the comment mapping was disabled. The hotfix for 7.3 is 
basically to enable these additional checks and disable the comment 
mapping even when assertions are disabled.

Impact: incorrect comments appearing in the source code after refactoring.

Risk: as the fix basically only changes a code path from 
assertions-enabled-only to always-enabled, the result should not be 
worse than an ordinary dev build. Two possible risks are: performance 
worse that in ordinary release build (but not worse than in an ordinary 
dev) and a very corner case behavioral change for code that was never 
tested with assertions enabled.
