Description (last modified by frank) (diff)
emerging 4.1.4 ose on gentoo here with following failure:
/var/tmp/portage/app-emulation/virtualbox-4.1.4/work/VirtualBox-4.1.4_OSE/ out/linux.amd64/release/obj/vboxjxpcom-gen/jxpcomgen/java/glue/Helper.java:123: error: name clash: unwrap(List<Integer>) and unwrap(List<Short>) have the same erasure public static int[] unwrap(List<Integer> vals) { ^ /var/tmp/portage/app-emulation/virtualbox-4.1.4/work/VirtualBox-4.1.4_OSE/ out/linux.amd64/release/obj/vboxjxpcom-gen/jxpcomgen/java/glue/Helper.java:135: error: name clash: unwrap(List<Long>) and unwrap(List<Short>) have the same erasure public static long[] unwrap(List<Long> vals) { ^ /var/tmp/portage/app-emulation/virtualbox-4.1.4/work/VirtualBox-4.1.4_OSE/ out/linux.amd64/release/obj/vboxjxpcom-gen/jxpcomgen/java/glue/Helper.java:147: error: name clash: unwrap(List<Boolean>) and unwrap(List<Short>) have the same erasure public static boolean[] unwrap(List<Boolean> vals) { ^ /var/tmp/portage/app-emulation/virtualbox-4.1.4/work/VirtualBox-4.1.4_OSE/ out/linux.amd64/release/obj/vboxjxpcom-gen/jxpcomgen/java/glue/Helper.java:159: error: name clash: unwrap(List<String>) and unwrap(List<Short>) have the same erasure public static String[] unwrap(List<String> vals) {
indeed, src/VBox/Main/glue/glue-java.xsl on line 2656 has illegal java:
public static short[] unwrap(List<Short> vals) { if (vals==null) return null; short[] ret = new short[vals.size()]; int i = 0; for (short l : vals) { ret[i++] = l; } return ret; } public static int[] unwrap(List<Integer> vals) { if (vals == null) return null; int[] ret = new int[vals.size()]; int i = 0; for (int l : vals) { ret[i++] = l; } return ret; } public static long[] unwrap(List<Long> vals) { if (vals == null) return null; long[] ret = new long[vals.size()]; int i = 0; for (long l : vals) { ret[i++] = l; } return ret; } . . .
Some more generic methods with the exact same erasure which is illegal java. Any sane fix for this ? Am I missing something ?
Change History

the fix is not difficult
just change unwrap(List<Integer> vals
to unwrapi
unwrap(List<long
to unwrapl
an so on
and after that go to glue dir and when call unwarp see if should be unwrapi , unwrapl etc
Note: See
TracTickets for help on using

I got same issue on Fedora rawhide, which chip Java 1.7
but no solution or patches appears to resolve this compile error, Just disable java or use java 1.6
