As ex-employee I can tell you that Nokia was surely a big proponent of Java, before LWT appeared, the Nokia UI framework was the best extension to J2ME, hardware accelerated on their devices.

They also add J2ME extensions for Symbian capabilities and N95 was the first handset to have real hardware acceleration to J2ME 3D features.

It was a big shock to everyone the communication to move beyond Java and C++ into C# and adopt WP7.
