Carsten Ziegeler commented on SLING-6502:
-----------------------------------------
Thanks [~olli]
The pax web bundles export javax.el in version 3 and javax.jsp in 2.3.1 - which
results in the jsp packages being imported and used by the scripting.jsp bundle
but not the javax.el one. And i guess that's what in turn creates the above
problem.
So I assume simply updating the embedded versions in scripting.jsp should solve
the problem.
Also not using pax web solves the problem. Unfortunately, even pax jetty is
importing javax.el , so removing even that single bundle does not work.
Of course importing everything from the outside should solve the problem as
well, however this might bring us into other version mismatch problems
