The DemuxCompositeELResolver optimization that was added in Mojarra 1.2.15
was not correctly ported forward to the 2.x releases. The
DemuxCompositeELResolver is present in 2.x. However, the corresponding
changes in ELUtils.java are missing.
As a result, all resolvers are added to both the root and property resolver
chains in DemuxCompositeELResolver, thus losing any optimization.
