Just that nobody has needed it until now.

Here's a version you can use right now:
/**
* Remove the item at index i from the ValueVector; move all the
* higher-numbered elements down.
*/
public final ValueVector remove(int i) throws JessException {
if (i < 0 || i >= m_ptr)
throw new JessException("ValueVector.set",
"Bad index " + i +
" in call to remove() on this vector:",
toStringWithParens());
if (i < (m_ptr - 1))
System.arraycopy(m_v, i+1, m_v, i, m_ptr-i);
m_v[--m_ptr] = null;
return this;
}
