I'm actually aware of this and the fix is going to be in the next
release. The patch involves replacing three methods in
jess/TokenVector.java with new versions:
final void clear() {
if (m_ptr > 0) {
Arrays.fill(m_v, 0, m_ptr, null);
m_ptr = 0;
}
}
final void removeElementAt(int i)
{
m_v[i] = m_v[m_ptr-1];
m_v[--m_ptr] = null;
}
final void removeElement(Token t)
{
for (int i=0; i<m_ptr; i++)
if (t.dataEquals(m_v[i]))
{
removeElementAt(i);
return;
}
}
