The code in OpenJDK should be mostly the same as in Oracle's proprietary
binaries; I believe the remaining differences these days are different
graphics & font renderers, and some tooling.

There are certainly com.sun.* classes. I just did a quick check
and the rt.jar I have for OpenJDK 8 contains 7,475 com.sun classes.

If there are particular classes/functionality you need to know are present
in OpenJDK, I'm happy to provide further confirmation to help your switchover.
