Can a jar which is compiled on old java version be used in new applications?

We are planning to upgrade our J2EE application, I worked with a lot of jars before and I know that the version mismatch can be a hard problem to debug. We have all the jars(internal to company and built by some other team so cannot recompile with latest version ) compiled using 1.6 jdk and we are bumping up our application version to 1.7, but we are planning to use 1.6 version jars in our app. Does this work well? If not what should I do to make it compatible?

I'm sure that it will work well but, need some expert opinion on this. Thank yo

As you can see on Oracle's homepage regarding compatibility of Java 1.7 it should be compatibale except for the following things

Binary Compatibility

Java SE 7 is binary-compatible with Java SE 6 except for the incompatibilities listed below. Except for the noted incompatibilities, class files built with the Java SE 6 compiler will run correctly in Java SE 7.
