[R-pkg-devel] Used package not updated - needs java < V 11

[Spencer Graves]

	 I suggest NOT using "XLConnect".  "sos" now uses WriteXLS.  "Ecfun" 
now uses "openxlsx".


	  Also, I received an email from CRAN maintainers months ago saying 
that "gdata" was being obsoleted.  It's still on CRAN with a date of 
2017-06-06 and a huge number of reverse dependencies.  The CRAN 
maintainers may have gotten someone to agree to take it over who just 
hasn't finished fixing whatever deficiencies it has.  However, you might 
see how difficult it might be to do without "gdata" as well.
