from the JDK method copy, which is a member of the
java.lang.reflect.Method class. The following code throws the
exception at the line 'Class[] out = new Class[l];':
/*
* Avoid clone()
*/
static Class[] copy(Class[] in) {
int l = in.length;
if (l == 0)
return in;
Class[] out = new Class[l];
for (int i = 0; i < l; i++)
out[i] = in[i];
return out;
}
You will notice that 'l' is < 0. 'l' is set by interogating the
length member of 'in' array, how is this possible? The 'in' is
constructed internally in the JDK code. I have checked the length of
all arrays I am passing to the JDK code and they are all > 0.
Thanks,
Michael
