   Hello Apache Struts Team.
   
   This PR is a re-target of PR #489 aiming the equivalent changes to the 2.6.x main branch (hopefully the cherry-picks and subsequent cleanup are OK).  Please see the original PR for background and discussion details.
   
   This PR attempts to add logic to call cleanup in the `release()` method for the Tag handler as well, but otherwise should be equivalent to the original PR for 2.5.x.
   
   There may be a better strategy/design to consider instead, but at least it provides a starting point.  Please let me know if anyone can see a cleaner solution.

> On some application servers, like glassfish, when handling jsp tag pooling, attribute values are cached or not reinitiallized.
> For example:
> {code:java}
> <s:textfield size="50">
>     <jsp:attribute name="placeholder">THIS TEXTFIELD SHOULD HAVE VALUE</jsp:attribute>
>     <jsp:attribute name="value">VALUE</jsp:attribute>
> </s:textfield>
> <s:textfieldsize="50">
>     <jsp:attribute name="placeholder">THIS TEXT FIELD SHOULDN'T HAVE VALUE</jsp:attribute>
> </s:textfield>{code}
>
