Updating for future jdk versions

Hi turbine devs,


I just went through and tested building fulcrum components with 
jdk-12.0.2 (latest) and pushed a couple of updates that allowed for some 
of the broken components to build.  Georg - json has some issues still 
that I did not work out that will need to be addressed.  Also 
commonsemail (move to attic?) makes a single call to a CORBA InputStream 
that would require either replacing or adding the required modules to 
the build profile.  However, I think this is one of several components 
we can probably move to the attic.

fulcrum-jetty was giving me some issues building just as is (test seemed 
to hang) but not sure if that is just my machine or something else.

I'm not sure what our roadmap looks like to move beyond Java8, but we 
should start thinking about it.  Hopefully this exercise is of help in 
that effort :-)
