Summary: ByteLookupTable and ShortLookupTable / index out of bounds
Original Submission: The following code throws an
ArrayIndexOutOfBoundsException:
public static void main(String[] args) {
byte[] data = {105, 104, 103, 102, 101, 100};
ByteLookupTable t = new ByteLookupTable(100, data);
// check 3-band source with 1-band lookup table
int[] src = new int[] {100, 101, 102};
int[] dst = t.lookupPixel(src, null);
}
This bug is triggered in the lookupPixel(src, dst) methods of both the
java.awt.image.ByteLookupTable and java.awt.image.ShortLookupTable classes when
(a) dst is null, and (b) the number of bands in the lookup table is less than
the number of elements in src.
Looking at the source code, it appears that 'dst' should be initialised with
'src.length' elements, rather than 'numComponents' elements.
Mauve tests are attached.
