Subject [jira] Updated: (HARMONY-2712) [classlib][awt][compatibility] java.awt.image.Raster.createBandedRaster(int,int,int,int,int[],int[],Point) throws ArrayIndexOutOfBoundsException while Ri throws NPE

Alexei Zakharov updated HARMONY-2712:
-------------------------------------

    Component/s:     (was: Classlib)
                 Non-bug differences from RI

Since RI behavior contradicts the spec here I'm moving this JIRA to non-bug-diff.

> RI throws unspecified NPE while Harmony throws specified ArrayIndexOutOfBoundsException.
API specification says: "ArrayIndexOutOfBoundsException - if bankIndices or bandOffsets is
null". This issue seems to be mostly RI problem. I think it is a non-bug difference from RI.

> If array1 is just empty (not null!) RI also throws ArrayIndexOutOfBoundsException while
Harmony throws IllegalArgumentException , which is correct. So it's RI's behavior contradicts
the spec.
