Oliver Lietz commented on SLING-6502:
-------------------------------------
[~rombert], should already be fixed by
[r1786631|https://svn.apache.org/r1786631].
[~cziegeler], [~fmeschbe]: The current setup of Scripting JSP, Apache Tomcat
6.0.14 JSP and EL API wrappers comes very close to what we had before. Root
issue is the unqualified import (without fixed version 2.1.0) of JSP and EL API
in Scripting JSP. Tying the imports to 2.1.0 works in general
([r1786606|https://svn.apache.org/r1786606]) and would allow usage of Apache
Tomcat 6.0.14 JSP and EL API in all deployments where JSP and EL API are not
already exported with version 2.1.0 (*preferred*), but fails with _taglib_
({{SlingJSPTaglibTest}}, therefore reverted in
[r1786631|https://svn.apache.org/r1786631]):
