this sounds like shell problems, not cat problems

if you still have problems, you should enable shell debugging (set -x) to 
track things down ... if you're still unable to solve your troubles, i'd 
suggest a general Linux/shell forum rather than the coreutils mailing list

you probably need to quote *.java to keep the shell from expanding it

that is not how input redirection works ... i dont know whether you're trying 
to feed the file "$SOURCE" into javac or pass the list of things in as an 
argument ... the former, just drop the "cat":
.../javac ... < $SOURCE
for the latter, inline it properly:
.../javac ... $(cat $SOURCE)
