Henri Yandell resolved STR-3021.
--------------------------------
Resolution: Fixed
svn ci -m "Applying patch from STR-3021. Thanks to Thomas Wilhelm for reporting
the bug wherein exceptions thrown in tiles-included JSPs cause includes to
happen twice. The change was to not consider an InvocationTargetException as a
debug item, but as an exception whose contents need to be rethrown. " tiles

> Tiles insert is evaluated twice if JSP error occures

> Project: Struts 1

> Components: Tiles
> Affects Versions: 1.3.5

> If an Exception is thrown in a tiles-included JSP the surrounding
> tiles-insert is processes twice. This most presumably due to a bug in
> TilesUtilImpl#doInclude(String uri, PageContext pageContext, boolean flush)
> where the InvocationTargetException is handled incorrectly. Every exception
> thrown from the executed inlcude-method will be throw wrapped into a
> InvocationTargetException so that include-method as well as
> pageContext.include(uri) is executed everytime a JSP-Error occures during an
> inlcude.
