This is fine. Amazon is just redistributing OpenJDK according to the terms of its license, which is indisputably legal. The problem with Android was that it was using, Harmony, a clean-room implementation of JDK whose license is incompatible with OpenJDK. It was believed at the time that APIs were not copyrightable, and thus that clean-room implementations were not derivative works. The courts disagreed. Now Google just uses OpenJDK for Android and they are back in the clear again.
