Java-mode Debug question ?

[Francis Belliveau]

I am running emacs Version 26.1 (9.0) on OSX 10.13.6
I know that I downloaded and installed this earlier this year and have not used 
Java-mode, or c-mode, with this version until today.

When I try entering Java-mode I get an error indicating that there is a 
problem, with a key-map.  This happens with c-mode also.  Clearly there is 
something wrong with the install, but I have no clue where to look for the 
problem.

Setting debug-on-error provides the following information:

Debugger entered--Lisp error: (wrong-type-argument keymapp nil)
  define-key(nil "\003\005" c-macro-expand)
  autoload-do-load((autoload "cc-mode" 889279 t nil) java-mode)
  command-execute(java-mode record)
  execute-extended-command(nil "java-mode" "java-mode")
  funcall-interactively(execute-extended-command nil "java-mode" "java-mode")
  call-interactively(execute-extended-command nil nil)
  command-execute(execute-extended-command)

Any help will be appreciated.

Thanks,
Fran
