Bug ID: 55158
Summary: Wasted work in AttributeNamesEnumerator constructor
Product: Tomcat 7
Version: 7.0.41
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org

patch
The problem appears in version 7.0.41 and in revision 1497999. I
attached a two-line patch that fixes it.
In the "AttributeNamesEnumerator" constructor, the loop over
"specials" keeps overriding "last" with "i". Therefore, only the last
written value is visible out of the loop and all the other writes and
iterations are not necessary. The patch iterates from the end of
"specials" and breaks the first time when "last" is set.
