I don't know, but the more you tell us, the more I believe that this is 
one screwed-up system.. ;-)

Try these 3 commands :


echo $PATH


find / -name java

and let us see the output

and then, just by curiosity, do

ls -l /opt/java/bin/java

and let us see that too

and, just for fun, try

java -version

and ditto
