Yes.

If you use portupgrade, you might get pkgdb complaining about apache-ant 
or somesuch depending on the linux-sun-jdk14 port, but that can be fixed 
easily by running 'pkgdb -F'.  All of the Java stuff should pretty much 
"just work"(tm) exactly the same with the native jdk14 port, although 
there may be one or two things that don't either crash or freeze up with 
the native JDK...

When you remove the linux-sun-jdk port, check /usr/local/etc/javavms for 
sanity.  Also check for environment variables like JAVA_HOME, JDK_HOME 
or CLASSPATH -- for best results those variables should (probably) be 
unset.  Most Java apps should be using /usr/local/bin/javavm which is a 
shell script that automatically substitutes whatever your favourite JVM 
is.  Those environment variables will override that behaviour, which is 
something you only want to do if (a) you know what you're doing and (b) 
that's what you specifically intend to do.

	Cheers,
