Hi s'marks,
You probably don't need to absolutify paths.
And you can easily handle multiple args.
(just for fun!)
Checks for javadoc comment; handles popular html entities; handles multiple
lines; handles both tt and code:
#!/bin/bash
find "$@" -name '*.java' | \
xargs -r perl -p0777i -e \
'do {} while s~^
*\*.*\K<(tt|code)>((?:[^<>{}\&\@]|&(?:lt|gt|amp);)*)</\1>~$_=$2;
s/</</g; s/>/>/g; s/&/&/g; "{\@code $_}"~mgie'
