/usr/portage/dev-java/sun-j2me-bin/sun-j2me-bin-2.2-r2.ebuild wants fetchresricted j2me_wireless_toolkit-2_2-update_1-linux.zip from http://java.sun.com/products/sjwtoolkit/download-2_2.html but this site now offers j2me_wireless_toolkit-2_2-update_2-linux.zip only. maybe required file is still downloadable, but sun sites are too crappy to investigate...
I'll take a look into it.
I've tested some midlets with update_2 and all works ok, bumped as -r3.
