That's weird.  readlink() returns a 28-byte path for me
(/usr/local/jdk1.5.0/bin/java).  When you run "java" what command is
that actually running?  My "java" points to /usr/local/bin/java which is
actually javawrapper.sh.  I suspect your "java" is either a link or an
alias to something else which is causing the file symlink not to point
to the fully-qualified path to the VM.
