I should be able to use a Java class anywhere and in the same way I use a CFC now, eg:

s = new java.lang.String("Yeah, bad example I know");

I should be able to specify Java class types in function argument type and return types too.

I should be able to extend Java types in CFML. I should be able to implement Java interfaces with a CFC, and have be able to use these CFCs in Java method calls expecting the given parent class / interface.

Definitely agree with this one. We need to leverage as much as we can off Java.

+1 anything that helps leverage core java constructs will make my job easier

Not only would I like the Java integration as described in this ticket, but also the ability to define via the CF Admin "...a pluggable cache architecture that allows you to write a Java adapter class that will connect to any underlying caching engine." (from I should be able to use any cache engine I want - it happens to be Couchbase btw. These caches should be able to be used for session and/or client storage.

There is so much that Java can do very well, and all of it should be dead simple in ColdFusion.

So many times I've said, "It's right there, why is it so hard?"

I like this idea but I don't like the idea of trying to work out whether I'm using a java type or a coldfusion type variables in a file with 2000 lines of spaghetti in it.

would help keep the language relevant if we could also use all the power of java

Something common when interacting with Java libs is the expectation for me to extend an abstract class and override a couple methods in it. I can do that now only by creating an actual java class, compiling it to a jar and adding it to my classpath. It would be great to be able to create a CFC that extends a Java class, but even BETTER to be able to declare the class on the fly like Java allows. It's actually a shame when Java offers a quicker, more concise syntax to something than CFML! Here's an example of some Java code that creates a class on the fly that extends another class, overriding a method: Authenticator authenticator = new Authenticator() { public PasswordAuthentication getPasswordAuthentication() { return (new PasswordAuthentication("user", "password".toCharArray())); } };

How's that "Needs Review" going, after two years?

+1 Might I suggest a prefix to the class path if you're using java to address the extremely valid concern raised on 07/03/2015. Component foo = new; Java foo = new,my.lib();

I agree with the syntax proposed by Adrian Moreno: foo = new;
