emerging 4.1.4 ose on gentoo here with following failure:

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 ?

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

Thanks for the hint. This should only apply to JDK 1.7.0.

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
