J2ME was king on mobile devices in Europe (at least). Moreover, SUN had licencing fees from J2ME and if I remember correctly, you could not use Java on mobile devices without paying fee to SUN. So, it was their source of income and Google abused that. Just check interview (many times referenced here in comments) with James Gosling to see what the feelins on SUN side were. At that point, they were already underdogs compared to Google. This is all about greedy Google business behaviour and I think with Oracle they just got nice sparing partner to play legal war games with. SUN was too nice for them.
