GLuint parameters are converted to java int paramters. This causes incorrect
values to be read on the java side for instance when performing selection. The
int array that the glSelectBuffer(int size, int[] buffer) method receives
contains values that are incorrect if they are not converted to long values
first (ie intValue & 0xFFFFFFFFL).

This will not be fixed. There is no way to efficiently map an integral C type to
a Java int type of a different size. You will have to manually zero-extend these
values. If you have suggestions on how to make this easier for the end user
(perhaps with a helper class) please file an RFE.
