7.1 HR Integration Review: #205774: Incorrect annotation marks

http://netbeans.org/bugzilla/show_bug.cgi?id=205774

Description:
org.netbeans.editor.Annotations.getLineAnnotations may return 
LineAnnotations for a different line than specified, due to an internal 
cache. This leads to an incorrectly placed annotation in some cases.

Fix:
Ensure that when returning cache-based value, the LineAnnotations belong 
to the correct line, falling back to the standard binary search if it 
does not.

Risk: minimal.

Changeset:
