More finding LISP

I find myself wondering about LISP as well as Preston:Preston L. Bannister ? Finding Lisp.

But I'm not sure how he squares these two paragraphs:

• "Both were written using UCI Lisp. [....] The folks in the Ada programming environment project generated an Ada parser, interpreter, compiler, and integrated editor for a subset of Ada in a remarkably small amount of time. This was only possible by leveraging off the Lisp environment. " AND
  
• " In fact the combination of Java and XML covers much the same ground"
  

I should have thought the ADA environment probably used features such as LISP macros etc. ; how do Java and XML help there?
