Suspicious 'System.arraycopy()' call
Reports suspicious calls to System.arraycopy()
.
Such calls are suspicious when:
the source or destination is not of an array type
the source and destination are of different types
the copied chunk length is greater than
src.length - srcPos
the copied chunk length is greater than
dest.length - destPos
the ranges always intersect when the source and destination are the same array
Example:
void foo() {
int[] src = new int[] { 1, 2, 3, 4 };
System.arraycopy(src, 0, src, 1, 2); // warning: Copying to the same array with intersecting ranges
}
