Summary

Correct the specification of JTabbedPane.insertTab() to say that an index of 0 is allowed.

Problem

The specification of JTabbedPane.insertTab() incorrectly states that the index parameter must be > 0. This is not only incorrect but inconsistent with the throws clause

Solution

Java Doc is updated for the index parameter range, from > 0 to >= 0.

Specification

class javax.swing.JTabbedPane

          * @param index the position to insert this new tab
    -     *       ({@code > 0 and <= getTabCount()})
    +     *        {@code (index >= 0 && index <= getTabCount())}
          *
          * @throws IndexOutOfBoundsException if the index is out of range
-     *         ({@code < 0 or > getTabCount()})
+     *         {@code (index < 0 || index > getTabCount())}
