Obviously ;)

Unfortunately, gjdoc now needs ANTLR [1] to do its job. While I could 
have simply put in antlr.jar into Kaffe's CVS tree, I decided to use the 
approach used by Julian Scheid in gjdoc's CVS and use an installed 
antlr.jar. In order to find ANTLR, the configure script executes a few 
tests that require the presence of a Java runtime. That's why I disabled 
  gjdoc by default again, as that interferes with bootstrapping on 
virgin systems.

The other solution would be to bite the bullet and put antlr.jar into 
CVS [2], or to merge it in as a whole chunk of source, and build it from 
scratch for gjdoc. Given that the ANTLR.jar detection approach has been 
very painful to merge in from gjdoc, I'd opt for the latter.
